Question

Which of the following statement is FALSE?

a. The free energy barrier in a chemical reaction must be overcome in order for products to form.
b. An increase in temperature can result in an increased reaction rate.
c. Lowering the free energy of the transition state can increase the reaction rate.
d. At a given temperature and time all molecules in a solution or a sample will have the same energy.
e. An enzyme can increase the reaction rate by lowering the activation energy.

Answer 1

correct option: D

Step-by-step explanation:

At any temperature and time all the molecule or sample does not have same energy because if we assume same energy then it should overcome the energy barrier at same time but it does not happen means they do not have same energy we also have seen in the chemical kinetics that very less number of molecule overcome the energy barrier means every molecule doen not same energy

hence given satement in option D is false
