Free energy changes for two reaction mechanism 'X' and 'Y are respectively - 15 and - 5 units. It implies that X is

A. Slower than Y

B. Faster than Y

C. Three times slower than Y

D. Three times faster than Y

Answer: Option B

Solution(By Examveda Team)

As, we know the relation $$\Delta G = \Delta {G^ \circ } + RTlnQ$$      where $$Q =$$  reaction quotient, higher the value of gibbs free energy change $$ \Rightarrow $$ higher is the value of $$Q \Rightarrow $$ faster is the rate of the reaction.
