Which energy graph represents the nonspontaneous transition of graphite into diamond?

Energy

Option (A)

A graph with Reaction progression on the horizontal axis and energy on the vertical axis. A line starts low on the vertical axis, runs briefly parallel to the horizontal axis, slopes up sharply, curves down a short distance, and levels out.

Explanation:

Critically looking into the

energy graph, the graph that represents the nonspontaneous transition of graphite into diamond is the graph that has the energy on the Y-axis i. e the horizontal axis with the Reaction progression on the X-axis i. e the horizontal axis.

Since the graph represent a non spontaneous transition. A non spontaneous reaction does not usually favour the formation of product under some given condition, endotermic reaction and also have decrease in their entropy.
