The first law of thermodynamics states that energy can neither be created nor destroyed, only altered in form.6. The value of Kp for the reaction at 500K 2NOCl(g) 2NO(g) + Cl2(g) is 1.8 × 10^-2bar^1 .8. The melting point and boiling point of lithium are higher that than other alkali metals. The hardness of lithium is higher than other metals13.a) statement that every chemical compound contains fixed and constant proportions (by mass) of its constituent elements. b) The limiting reagent in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed. 17. a)According to Fajan's rule, "Smaller is the cation, more is the covalent character.” b)A sigma bond is a single covalent bond formed from the direct overlap of orbitals. A pi bond is the parallel overlap of p orbitals.19.a)The Van der waals equation of 'n' moles of a real gas is (P+aV2). (V−b)=nRT. b)(1) the particles in a gas are in constant, random motion, (2) the combined volume of the particles is negligible, (3) the particles exert no forces on one another, (4) any collisions between the particles are completely elastic,​
