The rate of reaction between two reactants $A $ and $B$ decreases by a factor of $4$ if the concentration of reactant $B$ is doubled. The order of this reaction with respect to reactant $B$ is

Identify the reaction order from each of the following rate constants.

$(i)$ $k=2.3 \times 10^{-5} \,L \,mol ^{-1}\, s ^{-1}$

$(ii)$ $k=3 \times 10^{-4}\, s ^{-1}$

For a reaction $\mathrm{A} \xrightarrow{\mathrm{K}_4} \mathrm{~B} \xrightarrow{\mathrm{K}_2} \mathrm{C}$

If the rate of formation of $B$ is set to be zero then the concentration of $B$ is given by :

If in a certain reaction, two different reactants take part then

If the concentration is expressed in moles per litre, the unit of the rate constant for a first order reaction is

Half life of a reaction is found to be inversely proportional to the cube of its initial concentration. The order of reaction is
