Question

In the following rate constants were obtained in an experiment in which the decomposition of gaseous N2O5 was studied as a function of temperature. The products were NO2 and NO3.

a) Zero-order reaction
b) First-order reaction
c) Second-order reaction
d) None of the above

Answer 1

The rate constants can help determine the order of the reaction. A zero-order reaction has a rate constant independent of the reactant concentration, a first-order reaction has a rate constant proportional to the concentration of a single reactant, and a second-order reaction has a rate constant proportional to the square of a single reactant concentration.

Step-by-step explanation:

In this experiment, the rate constants for the decomposition of gaseous N2O5 were obtained as a function of temperature. The products of the reaction are NO2 and NO3. Based on the given information, we can determine the order of the reaction by analyzing the rate constants.

a) If the rate constant is independent of the concentration of the reactants, it is a zero-order reaction.

b) If the rate constant is directly proportional to the concentration of a single reactant, it is a first order reaction.

c) If the rate constant is directly proportional to the square of the concentration of a single reactant, it is a second-order reaction.

d) If none of the above conditions are met, then it is none of the above.
