The rate of a reaction increases sixteen times when the concentration of the reactant increases four times. The order of the reaction is
Assertion (A): The units of rate constant of a zero order reaction and rate of reaction are the same.
Reason (R): In zero order reaction, the rate of reaction is independent of the concentration of reactants.
The following experimental rate data were obtained for a reaction carried out at $$25^{\circ} \mathrm{C}$$
$$A_{(g)}+B_{(g)} \rightarrow C_{(g)}+D_{(g)}$$
| Initial $$\mathrm{[A_{(g)}]/mol~dm^{-3}}$$ | Initial $$\mathrm{[B_{(g)}]/mol~dm^{-3}}$$ | Initial rate/mol $$\mathrm{dm^{-3}s^{-1}}$$ |
|---|---|---|
| $$3.0 \times 10^{-2}$$ | $$2.0 \times 10^{-2}$$ | $$1.89 \times 10^{-4}$$ |
| $$3.0 \times 10^{-2}$$ | $$4.0 \times 10^{-2}$$ | $$1.89 \times 10^{-4}$$ |
| $$6.0 \times 10^{-2}$$ | $$4.0 \times 10^{-2}$$ | $$7.56 \times 10^{-4}$$ |
$$\text { What are the orders with respect to } \mathrm{A}_{(\mathrm{g})} \text { and } \mathrm{B}_{(\mathrm{g})} \text { ? }$$
Assertion (A): For a zero order reaction the unit of rate constant and rate of reaction are same.
Reason (R) : Rate of reaction for zero order reaction is independent of concentration of reactant.
