Chemical Kinetics - CHM2046

These flashcards cover fundamental concepts in chemical kinetics, including reaction rates, stoichiometry, and reaction orders based on provided lecture notes.

What is the rate of reaction based on the change in concentration of H2 in the example provided?

The rate of reaction based on H2 is 7.0 x 10^-3 M/s.

What is the rate of fluorine change based on the rate of product formation of 3.2 x 10^2 M/s for the reaction involving NO2 and F2?

The rate of fluorine change is -1.6 x 10^2 M/s.

For the reaction A + 2B → C, if the initial rate is 0.100 M/s, what is the rate of change of B?

The rate of change of B is -0.200 M/s.

If the rate of reaction for N2O decomposition is 0.022 M/s, what is the rate of decrease in concentration of N2O?

The rate of decrease in concentration of N2O is 0.022 M/s.

In the reaction 4NH3 + 5O2 → 4NO + 6H2O, if the consumption rate of NH3 is 4.23 x 10^-4 mol L^-1 s^-1, how do you calculate the rates of O2 consumed and NO produced?

Use stoichiometry based on the balanced equation.

Given a rate of disappearance of N2O5 as 4.0 x 10^-6 mol L^-1 s^-1, how does that relate to the rate of appearance of the products?

Apply the stoichiometric coefficients from the decomposition reaction to find rates of product formation.

What is the relationship between the order of reaction and how concentration affects rate for zero, first, and second order reactions?

Zero order: rate is constant; first order: rate is proportional to concentration; second order: rate is proportional to the square of concentration.

If doubling [A] for a reaction A → products causes the rate to double, what is the order of the reaction?

The order of the reaction is first (n=1).

How is the overall order of reaction determined from a rate law that includes two reactants A and B?

The overall order is the sum of the individual orders with respect to each reactant.

In a series of experiments, if the concentration of A is varied and the rate of reaction is recorded, how can the order of the reaction with respect to A be determined?

By analyzing how changes in [A] affect the rate of reaction to establish the relationship.
