Question

PEC diagram is the graph shown in the right

Refer to the PEC diagram Which statement best describes which state is favored at low temperatures? "A" is favored at low T because lowering the temperature favors the state of lowest PE "A" is favored at low T because lowering the temperature favors the state of higher number of configurations. "C" is favored at low T because lowering the temperature favors the state of highest number of configurations "C" is favored at low T because lowering the temperature favors the state of highest PE.

Explanation / Answer

Answer:

A is favoured at low T because lowering the temperature favours the state of lowest PE.

Explanation: At low temperature energetically more stable configurations are favoured because random motions are reduced hence holding the system in a state of lower potential energy (PE) and to lower number of configurations.
