Question

If the rate equation for a reaction is \( \frac{dx}{dt} = k[H]^{1/2}[B]^{1/2} \), the order of the reaction is

• A. 2
• B. \( \frac{1}{2} \)
• C. \( \frac{3}{2} \)
• D. 1

Hint:

The order of a reaction is determined by the sum of the exponents in the rate law.

Answer 1

The Correct Option is C

Step 1: Understanding the rate law.
The rate equation for the given reaction is: \[ \frac{dx}{dt} = k[H]^{1/2}[B]^{1/2} \] To determine the order of the reaction, we add the exponents of the reactant concentrations: \[ \text{Order} = 1/2 + 1/2 = 1 \] The total order of the reaction is 1. Hence, the correct answer is (C). Step 2: Conclusion.
The order of the reaction is \( \frac{3}{2} \).
