c
Formula: \(a A+b B \rightarrow c C+d D\)

\({\text {Rate}=\frac{d R}{d T}}\)

\({=\alpha[A]^{x} \cdot[B]^{y}}\)

\({=k[A]^{x} \cdot[B]^{y}}\)

\(\mathrm{K}=\) rate constant

Rate, \(r_{1}=k[A]^{2}[B]^{3}\)

On doubling the concentration, we have

\(r_{2}=k[2 A]^{2}[2 B]^{3}\)

\(=32 k[A]^{2}[B]^{3}=32 r_{1}\)
