STANDARD Chemistry Order of Reaction MCQ Question

Type: MCQ-numerical-Medium-Class 12

Find the values of A, B and C in the following table for the reaction X + Y → Z. The reaction is of first order w.r.t. X and zero w.r.t. Y.

A

A = 0.2 mol L⁻¹, B = 8 × 10⁻² mol L⁻¹ s⁻¹, C = 0.1 mol L⁻¹

B

A = 0.4 mol L⁻¹, B = 4 × 10⁻² mol L⁻¹ s⁻¹, C = 0.2 mol L⁻¹

C

A = 0.2 mol L⁻¹, B = 2 × 10⁻² mol L⁻¹ s⁻¹, C = 0.4 mol L⁻¹

D

A = 0.4 mol L⁻¹, B = 2 × 10⁻² mol L⁻¹ s⁻¹, C = 0.4 mol L⁻¹

Correct Answer

Option A

Detailed Explanation

Since the reaction is first order with respect to X and zero order with respect to Y, the rate is directly proportional to [X]. By comparing the initial rates and concentrations, we can determine the values of A, B, and C.
