Explanation / Answer

We Know that :        The Equation is :            2NO(g) + O2(g) ------>2NO2(g)          Rate = K [ NO ]2 [ O2]-2         1.41 x10-2 / [ 0.0126 ]2 [ 0.0125]-2    = K          K = 0.01387 Rate = - 1 / 2 [ NO ] / t   =  - [ O2 ] /t = + 1 / 2 [ NO2 ] / t           Rate of the disappearence of NO = 0.02 M            Rate of the disappearence of O2 = 0.0375 M         1.41 x10-2 / [ 0.0126 ]2 [ 0.0125]-2    = K          K = 0.01387 Rate = - 1 / 2 [ NO ] / t   =  - [ O2 ] /t = + 1 / 2 [ NO2 ] / t           Rate of the disappearence of NO = 0.02 M            Rate of the disappearence of O2 = 0.0375 M
