The reaction , N2O5 (in CCl4) ➡ 2NO2 + 1/2 O2 (g) is first order in N2O5 with rate constant 6.2 × 10-4 s-1 . What is the value of rate of reaction when [N2O5] =1.25 mol L-1 ?

Given : First order reaction
 
 N2O5 (in CCl4) ➡ 2NO2 + 1/2 O2 (g) 

K = 6.2 × 10-4 s-1​ 

Rate = K [N2O5]
Rate = ​ 6.2 × 10-4 s-1​× 1.25 ​=7.75 ​​× 10-4  mol L-1 s-1
