HCl can be produced by the exothermic reaction H2(g)+2ICl(g)→2HCl(g)+I2(g) . A proposed mechanism for the reaction has two elementary steps as shown below.

Step 1: H2(g)+ICl(g)→HI(g)+HCl(g) (slow)

Step 2: HI(g)+ICl(g)→HCl(g)+I2(g) (fast)
(d) Write a rate law for the overall reaction that is consistent with the proposed mechanism.

The rate of reaction can be given by Rate =  k [tex]\rm H_2] [HCl][/tex].

The activation energy of step 1 is higher as compared to the activation energy of step 2.

  • In the proposed mechanism for the formation of HCl, two steps have been followed.

The rate of reaction has been determined by the slow step.

Thus the rate will be:

Rate = k [tex]\rm H_2] [HCl][/tex],

where k is the rate constant.

  • In the incomplete diagram, the wave for step 1 has higher activation energy as it has been a slow step.

The activation energy of step 2 has been lower as compared to step 1.
