Question

3.The rate constant for the reaction
2N2O5(g) = 2N2O4(g) + O2(g)
Is 4.98 x 10 -4 s-1. The order of reaction is

a.2
b.1
c.0
d.3​​

Answer 1

Answer:

b. 1

Explanation:

since unit of rate constant is given by above relation.

where: n abbreviat for order of the reaction.

when n=1, unit comes out to be "per second"

hence correct option is "b"
