The reaction of chloromethane with hydroxide ion at 30 oC has a ΔGo value of -21.7 kcal/mol. What is the equilibrium constant for the reaction?
Step 1 of 5</p>
For a reaction of chloromethane with hydroxide ion:
The above reaction is belongs to reaction. So, the rate is depends upon both nucleophile and chloromethane.
Here ‘’is known as the rate constant for the reaction. The reaction is said to second order overall. That is first order with respect to and first order with respect to.
Step 2 of 5</p>
The change in free energy in going from starting materials to products, is related to the equilibrium constant, for the change by the relation,
Here, is called the free energy of activation for a reaction.
‘’ is the universal gas constant.
‘’ is the absolute temperature.
Step 3 of 5</p>
That is larger the decrease in free energy (minus) on going from starting materials to products, the larger the value of , and the equilibrium lies in favour of the products. The position of minimum free energy thus corresponds to the attainment of equilibrium by starting materials or products. In a reaction for which there is no free energy change, which corresponds to conversion of starting materials into products. Increasing positive values of rapidly decreases value of , corresponding to extremely little conversion into products, while increasing negative values of corresponds to rapid increase of values.
