Question

Select incorrect statements about chemical catalysts.

• A. They are not consumed during the chemical reaction
• B. They cannot make nonspontaneous reactions occur
• C. They do not have to the same phase as the reactant molecules
• D. They shift equilibrated reactions to the product's side
• E. Enzymes are biological catalysts

Answer 1

Answer: (D)

They shift equilibrated reactions to the product's side

The statement (D) is incorrect about chemical catalysts.
They do not shift equilibrated reactions to the product's side.
A catalyst increases the rate of the forward and reverse reaction to equal extent. However, it does not affect the value of the equilibrium constant.
Thus, the equilibrium is quickly attained but the position of the equilibrium is not affected.
