Write the rate equation for the reaction $2A + B \to C$ if the order of the reaction is zero.

(N/A) The rate law expression for a reaction $aA + bB \to \text{products}$ is given by $\text{Rate} = k[A]^x[B]^y$,where $x+y$ is the order of the reaction.
Given that the order of the reaction is $0$,the sum of the exponents $x+y = 0$. Since the reaction involves both $A$ and $B$,the individual orders are $x=0$ and $y=0$.
Therefore,the rate equation is $\text{Rate} = k[A]^0[B]^0$.
Since any value raised to the power of $0$ is $1$,the equation simplifies to $\text{Rate} = k$.
