Question

Why does diamond not spontaneously convert into graphite at room temperature despite graphite being thermodynamically more stable?
Options
A The reaction possesses a very high activation energy barrier
Correct Answer
B The overall enthalpy change for the conversion is highly positive
C Graphite has fewer available microstates than diamond at 298 K
D The conversion violates the First Law of Thermodynamics
Correct Answer

Option A is the correct answer.

Detailed Explanation

The conversion of diamond to graphite is thermodynamically spontaneous but kinetically extremely slow due to a very high energy barrier.
