The initial rates of reaction

3 \mathrm{A}+2 \mathrm{B}+\mathrm{C} \longrightarrow

Products, at different initial concentrations are given below:

\begin{array}{cccccccccccccccccccc} {{\text{Initial rate,}}}&{{{\left[ {\text{A}} \right]}_0},{\text{M}}}&{{{\left[ {\text{B}} \right]}_0},{\text{M}}}&{{{\left[ {\text{C}} \right]}_0},{\text{M}}} \\ {{\text{M}}{{\text{s}}^{ - 1}}}&{}&{}&{} \\ {5.0 \times {{10}^{ - 3}}}&{0.010}&{0.005}&{0.010} \\ {5.0 \times {{10}^{ - 3}}}&{0.010}&{0.005}&{0.015} \\ {1.0 \times {{10}^{ - 2}}}&{0.010}&{0.010}&{0.010} \\ {1.25 \times {{10}^{ - 3}}}&{0.005}&{0.005}&{0.010} \end{array}

The order with respect to the reactants,

\mathrm{A}, \mathrm{B}

and

\mathrm{C}

are respectively

View answer and explanation

Correct option: D

2, 1,0

The correct answer is D (2, 1, 0) because the rate is second order with respect to A, first order with respect to B, and zero order with respect to C, based on the given experimental data.
