HCl can be produced by the exothermic reaction H2(g)+2ICl(g)→2HCl(g)+I2(g) . A proposed mechanism for the reaction has two eleme
ntary 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.
(e) On the incomplete reaction energy diagram below, draw a curve that shows the following two details.
The relative activation energies of the two elementary steps
The enthalpy change of the overall reaction

Answer : The value of for
is
.
Solution : Given,
Solubility of in water =
The barium carbonate is insoluble in water, that means when we are adding water then the result is the formation of an equilibrium reaction between the dissolved ions and undissolved solid.
The equilibrium equation is,
Initially - 0 0
At equilibrium - s s
The Solubility product will be equal to,
Now put all the given values in this expression, we get the value of solubility constant.
Therefore, the value of for
is
.
