The heat capacities of a substance have been defined as C, (~~}, C, (~~), Use the defining relationship between Hand 0 and the fact that fJ and 0 for ideal gases are functions only of temperature to prove that C" = Cv + R for an ideal gas.

Friday, February 19, 2016 Chemistry 1102 Notes (2/15-2/19) Chapter 13: Chemical Kinetics - Kinetics - speed/rate at which a reaction takes place • Measured by: - increase in products or - decrease in reactants - Slope & Rate: • Slope = ∆Y/∆X • Rate = ∆ [product] OR [reactant]/∆ t (time in seconds) • Slope = Rate • ∆ [product] / ∆ t slope is a negative number • ∆ [reactant / ∆ t slope is a positive number • All rates should be reported as a positive number • Rate drops as time passes - Initial Rate: t = 0 (beginning of reaction) • The initial rate is the best indicator of rate - Reaction Rates & Stoichiometry: • aA+bB cC+dD • Rate = -(1
