Which statement most accurately describes the behavior of a catalyst?
A. A catalyst increases the ∆G of a reaction and hence the forward rate.
B. A catalyst reduces the ∆H of a reaction and hence the temperature needed to produce products.
C. A catalyst reduces the activation energy for a reaction and increases the rate of a reaction.
D. A catalyst increases the equilibrium constant and final product concentrations.
Answer (2)
the a answer to the statement is between B and D
A catalyst increases the reaction rate by lowering the activation energy required, without affecting the overall energy changes of the reaction. The correct answer that describes the behavior of a catalyst is option C: it reduces the activation energy and increases the reaction rate. Therefore, catalysts help reactions occur faster but do not change the equilibrium position or concentrations of products.
