Published on: August 13, 2026

In the reaction at any time t was found to be 2.4 x 10-4 mole L-1 min-1 with rate constant 4.4 x 10-4 min-1.Hence at the same time t and the corresponding rate constant of the reaction respectively would be

A
1.2 x 10-4 mole L-1 min-1, and 2.2 x 10-4 min-1
B
1.2 x 10-4 mole L-1 min-1, and 8.8 x 10-4 min-1
C
4.8 x 10-4 mole L-1 min-1, and 2.2 x 10-4 min-1
D
2.4 x 10-4 mole L-1 min-1, and 4.4 x 10-4 min-1

The correct answer is:
A

For 4 moles of NO2 formed, 2 moles of N2O5 consumed in a given time interval, so the rate of consumption of N2O5 must be half of the rate of formation of NO2, Rate constants w.r.t. these two rates will also have the same relationship. So. The choice is the correct answer.
