1.	If the substrate is given in molar concentration how would you define it’s Molarity and Molality based on the temperature condition?(a) Molarity and Molality both will change on effect of temperature(b) Molarity will change but not Molality(c) Molality will change but not Molarity(d) Normality of the reaction will changeThis question was addressed to me in homework.This interesting question is from Data Analysis in section Presentation and Analysis of Data of Bioprocess Engineering
Answer» Right CHOICE is (b) Molarity will CHANGE but not Molality The explanation: Molarity is the number of moles of solute per kilogram of the Solvent. That is because molarity does not depend on temperature, (neither on number of moles of solute nor MASS of solvent will be AFFECTED by changes of temperature). While molarity changes as temperature changes because molarity is affected by temperature. This is because it is BASED on the volume of the solution, and the volume of a substance will be affected by changes in temperature.
