2 C4H6 -----------> C8H12
based on the above data ,
this is 2nd order reaction .
k = 1 / t [1 / At - 1 / Ao]
= 1 / 1600 [1 / 5.04 x 10^-3 - 1 / 1.00 x 10^-2]
= 0.0615 M-1s-1
initial concentration Ao = 1.00 x 10^-2 M
time = 7512 sec
k = 1/t [1 / At - 1 /Ao]
0.0615 = 1/7512 [1 / At - 1/1.00 x 10^-2]
At = 1.78 x 10^-3
concentration = 1.78 x 10^-3 M
