Which set of conditions describes a reaction that is least likely to proceed?

Question

Quizplus · Accepted Answer

An endothermic reaction absorbs heat, which makes it less likely to occur spontaneously. Decreasing entropy also decreases the likelihood of a reaction occurring. High activation energy means that a greater amount of energy is required to initiate the reaction, further decreasing the likelihood of the reaction occurring. Overall, these conditions make the reaction least likely to proceed.
