Q. For the reaction $2A + B \rightarrow A_{2}B$, the rate Law given is
A) $k\lbrack 2A\rbrack\lbrack B\rbrack$
B) $k\lbrack A\rbrack^{3}$[B]
C) $k\lbrack A\rbrack\lbrack B\rbrack^{3}$
D) $k\lbrack A\rbrack^{2}$[B]
Explanation
(d)
For the reaction,$\ 2A + B \rightarrow A_{2}B$
According to rate laws,
Rate $\propto \$concentration of reactants
$rate = k\lbrack A\rbrack^{2}\lbrack B\rbrack$
Where, k=rate constant
