The reaction profile for a reversible, exothermic reaction in the presence and absence of a catalyst is shown below.
Which of the following statements correctly describes this system?
The catalyst increases the rate of the forward reaction by lowering the potential energy of the uncatalysed transition state T1T_1T1.
The rate-determining activation energy for the reverse catalysed reaction is represented by the energy difference between the 'Products' level and peak T3T_3T3.
The reaction intermediate III is more stable than the transition states T2T_2T2 and T3T_3T3.
The catalyst increases the value of the equilibrium constant (KcK_cKc) because the forward activation energy is lowered.
