1.	What do you mean by adiabatic reaction?(a) Constant Energy(b) Constant temperature(c) Constant Pressure(d) Constant workThe question was asked in quiz.This intriguing question originated from Equilibrium Constants and Conversions topic in section Applications of Thermodynamic in Unit Processes of Unit Processes
Answer» Right CHOICE is (a) Constant Energy For EXPLANATION: Adiabatic reaction takes place when CHANGE in energy is zero i.e., is no change in heat and energy of the body.

2.	What takes place when reactants are in excess:(a) Equilibrium(b) Forward reaction(c) Backward reaction(d) None of the mentionedI have been asked this question during a job interview.I want to ask this question from Equilibrium Constants and Conversions in section Applications of Thermodynamic in Unit Processes of Unit Processes
Answer» Right choice is (b) Forward reaction Easiest EXPLANATION: Forward reaction is a type of reaction where thereactants are in excess and hence the equilibrium MOVES forward to COMPLETE the reaction.

3.	Are Sensible heat and Latent heat same? State whether the statement is true or false.(a) True(b) FalseThe question was asked during an interview.I'm obligated to ask this question of Equilibrium Constants and Conversions topic in chapter Applications of Thermodynamic in Unit Processes of Unit Processes
Answer» Right choice is (b) False Easy explanation: Sensible HEAT is the amount of energy stored, WHEREAS Latent heat is the amount of energy needed to CHANGE the state of element WITHOUT any change in TEMPERATURE.

4.	What happens in backward reaction?(a) Both reactants and products are equal(b) Reactant is in excess(c) Product is in excess(d) Needs catalystThis question was posed to me in an online quiz.This key question is from Equilibrium Constants and Conversions in chapter Applications of Thermodynamic in Unit Processes of Unit Processes
Answer» The correct option is (C) Product is in excess For explanation: A backward reaction is a type of reaction where, the product is in more QUANTITY, so to attain EQUILIBRIUM reaction MOVES backward.

5.	What is ‘Df (delta f) :(a) Standard heat of reaction(b) Standard heat of product(c) Standard heat of combustion(d) Standard heat of formationI have been asked this question in an internship interview.My doubt stems from Equilibrium Constants and Conversions topic in chapter Applications of Thermodynamic in Unit Processes of Unit Processes
Answer» CORRECT OPTION is (d) Standard heat of formation For EXPLANATION I would SAY: The amount of energy required to FORM the element is ‘Df’ called as Standard heat of formation.

6.	The change in enthalpy of a system is called:(a) Heat of reaction(b) Standard heat of(c) Heat absorbed(d) None of the mentionedThe question was posed to me in class test.This key question is from Equilibrium Constants and Conversions topic in chapter Applications of Thermodynamic in Unit Processes of Unit Processes
Answer» The CORRECT CHOICE is (a) Heat of reaction For EXPLANATION: The change in enthalpy of a system when a reaction OCCURS, at a constant pressure is CALLED heat of reaction.

7.	Which energy a substance possesses due to motion and configuration of its atoms, molecules?(a) Potential energy(b) Kinetic energy(c) Internal energy(d) Surface energyI had been asked this question in semester exam.I want to ask this question from Equilibrium Constants and Conversions in division Applications of Thermodynamic in Unit Processes of Unit Processes
Answer» Right OPTION is (c) Internal ENERGY The best explanation: Internal energy a substance POSSESSES due to motion and configuration of its atoms, MOLECULES, it is due to motion and placing of particles within the structure.

8.	Heat flow as a result of what?(a) Pressure difference(b) Concentration gradient(c) Temperature gradient(d) None of the mentionedI had been asked this question during an interview for a job.Question is from Equilibrium Constants and Conversions in portion Applications of Thermodynamic in Unit Processes of Unit Processes
Answer» Right option is (c) TEMPERATURE gradient The best explanation: Heat is a form of energy that flow DUE to difference in temperature between the TWO areas or surfaces of CONSIDERATION.

9.	What is first law of Thermodynamics called?(a) Jacob’s law(b) Fick’s law(c) Energy law(d) None of the mentionedI have been asked this question during an online exam.My doubt is from Equilibrium Constants and Conversions in section Applications of Thermodynamic in Unit Processes of Unit Processes
Answer» The correct answer is (b) FICK’s law For explanation: The FIRST law of thermodynamics is: energy can NEITHER be created nor destroyed, it transforms from ONE FORM to another.
