Comprehension Dinitrogen pent oxide decompose to NO2 and O2 following first order kinetics N2O5(g) ( 2NO2 + O2 (g) 0.2 mole of N2O5 was taken in 2L vessel and heating at 200 K. The concentration of N2O5 is measured at different intervals. Following graphs A and B were obtained from the data. Slope of straight line in graph (B) is – 6670. Calculation the activation energy for the reaction.

The concentration of N2O5 is measured at different intervals. Following graphs A and B were obtained from the data. The time required for reaction to complete up to 99.9%?
ASSERTION(REASON A. NO2 + CO ( CO2 + NO rate = k [NO2]2 The rate is independent of concentration of CO. R. The rate does not depends upon [CO] because it is involved in fast step
Both A and R are true and R is correct explanation of A
Both A and R are true and R is not correct explanation of A
A is true, R is false
A is false, R is true
