The following data were obtained for the decomposition of N2O5 in CCl4 at 45 °C:
a. What is the order of the reaction with respect to (WRT) dinitrogen pentoxide?
b. What is the value of k?
c. What is the value of the half-life for the reaction in minutes?

a)

b)

c)

Explanation:

Complete question

(min)0         135          342           683             1693

c {M}2.081.91          1.67                   1.35              0.57

Solution -

a) One this clear from the data provided and it is that rate of the reaction does not remain constant with time and hence it is not a zero order reaction. Thus, the equation for first order reaction is

b) Rate of reaction

Substituting the given values in above equation, we get -

c) Value of the half-life for the reaction in minutes

Substituting the given values in above equation, we get -

per minute

thats how its supposed to be
