Which of the following can help predict the rate of a reaction if the standard Gibbs free energy of reaction (gibbs free energy change ) is known?

A

Equilibrium constant

B

Change in enthalpy

C

change in internal energy

D

Heat liberated during the course of reaction in calorimeter

Text Solution

Verified by Experts

The correct Answer is:
A
`because Delta G^(@)` (Gibbs free energy) is related to K (equilibrium constant) as follows:
`Delta G^(@)= -2.303RT log_(10)K`
where, R= Gas constant
T= Temperature in Kelvin By knowing the value of K we can find out rate of a reaction. (a) is the correct answer.
