An elementary reaction between $A$ and $B$ is a second order reaction. Which of the following rate equations must be correct?
$A(g) + 2B(g) \to $ product is a elementary reaction, which of the following is incorrect.
Velocity constant $K$ of a reaction is affected by
The rate law of the reaction $A + 2B \to $Product is given by $\frac{{d[dB]}}{{dt}} = k[{B^2}]$. If $ A$ is taken in excess, the order of the reaction will be
The rate law for a reaction between the substances $ A $ and $B$ is given by, rate $= k{[A]^n}{[B]^m}$. On doubling the concentration of $A$ and halving the concentration of $B$, the ratio of the new rate to the earlier rate of the reaction will be as
