A
In endothermic reaction reactant molecules have lower energy than product molecules
B
Energy of activated complex is higher than the energy of reactants
C
Energy of activation of a reaction is different from energy of activation with catalyst for the same reaction
D
Rate of reaction decreases with rise in temperature
Correct Answer
Rate of reaction decreases with rise in temperature
Detailed Explanation
4. Rate of reaction decreases with rise in temperature
In most cases, the rate of a reaction increases with a rise in temperature due to the increase in the kinetic energy of the reactant molecules, which leads to more frequent and energetic collisions, thereby increasing the likelihood of successful collisions and a faster reaction rate. This phenomenon is described by the Arrhenius equation, which shows that the rate constant of many reactions increases with temperature.
