Select the correct statement
For a general reaction $A \to B$, plot of concentration of $A$ vs time is given in figure. Answer the following question on the basis of this graph.
$(i)$ What is the order of the reaction ?
$(ii)$ What is the slope of the curve ?
$(iii)$ What are the units of rate constant ?
Select the rate law that corresponds to the data shown for the following reaction $A+ B\to C$
Expt. No. | $(A)$ | $(B)$ | Initial Rate |
$1$ | $0.012$ | $0.035$ | $0.10$ |
$2$ | $0.024$ | $0.070$ | $0.80$ |
$3$ |
$0.024$ |
$0.035$ | $0.10$ |
$4$ | $0.012$ | $0.070$ | $0.80$ |
If doubling the initial concentration of reactant doubles $t_{1/2}$ of reaction, the order of reaction is
The reaction $2NO + Br_2 \rightarrow 2NOBr,$ follows the mechanism given below
$(I)$ $NO + Br_2 \rightleftharpoons NOBr_2 $ ........ Fast
$(II)$ $NOBr_2 + NO \rightarrow 2NOBr$ ......... Slow
The overall order of this reaction is
