The rate equation determined experimentally for this reaction: (CH3)3―C―Br + H2O → (CH3)3―C―OH + HBr, is Rate = k[(CH3)3CBr] Hence it is which of the follwing?
Correct answer: B. Pseudo First Order
- A. Fractional Order
- B. Pseudo First Order
- C. First Order
- D. Second Order
Explanation
Explanation:The reaction is pseudo first order. Water is in excess as it is the solvent as a result will not affect the reaction order. If we don't take water in consideration the order of reaction is 1, because the exponent of [(CH3)3-C-Br] is one. As water is not taken into consideration the reaction is pseudo first order.

About Order of Reaction
Reaction order shows how the rate depends on the concentration of each reactant, as expressed in the rate law. Coverage includes zero, first and second-order reactions, integrated rate equations, half-life, units of rate constants and the distinction between overall order and molecularity.
