Ответ:
The concentration of X after 155 seconds is 0.13 M
Explanation:
Integrated rate law for second order kinetics is given by:
a= concentration left after time t = ?
k = rate constant =![0.035M^{-1}s^{-1}](/tpl/images/0572/1335/9af38.png)
t = time of decmposition = 155 s
Thus the concentration of X after 155 seconds is 0.13 M
