Question

The 1st order reaction is completed in 10mins. Calculate the rate constant K. ​

Answer 1

Answer:

First-Order Reactions

A first-order reaction depends on the concentration of one reactant, and the rate law is: r=−dAdt=k[A] r = − dA dt = k [ A ] .

r=−d[A]dt=k[A]

2N2O5(g)→4NO2(g)+O2(g)

Rate=k[N2O5]m.

rate=k[N2O5]1=k[N2O5]

1.4×10−3=k(0.020)

k=0.070s−1.
