Question

Q15. Choose the incorrect statement.
(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

FirstInTest · Accepted Answer

Correct answer: d. An increase temperature increases the reaction rate. When temperature is increased, the kinetic energy of the molecules also increase. Because of higher kinetic energy, the number of particles that possess the minimum energy also increases thereby more particles will collide and react.
