Q. The reaction $A_{\left(\right. g \left.\right)}+2B_{\left(\right. g \left.\right)} \rightarrow C_{\left(\right. g \left.\right)}+D_{\left(\right. g \left.\right)}$ is an elementary process. In an experiment, the initial partial pressure of $A\&B$ are $P_{A}=0.6\&P_{B}=0.8atm$ , when $P_{C}=0.2atm$ the rate of reaction relative to the intial rate is:
