Question

Which statement is NOT correct? a. An activated complex has higher energy than any molecule contributing to it. b. If the forward reaction is endothermic, the reverse reaction will be exothermic. c. Activation energy is the same in the forward and reverse direction. d. The activated complex will be the highest on the reaction energy diagram. e. In an endothermic reaction, the activation energy is usually greater than the change in enthalpy.

Answer 1

Answer:

c. Activation energy is the same in the forward and reverse direction.

Explanation:

Activation energy is the same in the forward and reverse direction is NOT correct. However, an activated complex has higher energy than any molecule contributing to it, if the forward reaction is endothermic, the reverse reaction will be exothermic, the activated complex will be the highest on the reaction energy diagram, and in an endothermic reaction, the activation energy is usually greater than the change in enthalpy IS CORRECT.

Answer 2

Answer:

C.Activation energy is the same in the forward and reverse direction.

Explanation:

All these are true statements expect for option "C"
