Chapter 6: Q. 12 P (page 174)

Which reaction is faster, one with ${ΔG}^{#}$ = +45 or one with ${ΔG}^{#}$ = +70?

Short Answer

Expert verified

The reaction with ${ΔG}^{#}$ = + 45is a faster reaction.

Step by step solution

Spontaneous reaction

Reactions that proceed without an external energy supply are called a spontaneous reaction.

For a reaction to be spontaneous, it needs to have a negative value of Gibbs free energy.

Also, for the reaction to be spontaneous, the value of ${ΔS}^{°}$ needs to be positive

Rate of reaction and ΔG# value

A fast reaction has a small ${ΔG}^{#}$ value. It means that smaller the value of ${ΔG}^{#}$ the rate of reaction is higher.

In the above case, there are two values for ${ΔG}^{#}$ —one is +45 and the second one is +70. Out of which +45 is thesmaller value so the reaction with ${ΔG}^{#}$ = +45 is thefaster reaction.
