Rate law equation for a reaction is $R=k[x][y]$, rate of reaction doubles when

Rate law equation for a reaction is $R=k[x][y]$, rate of reaction doubles when
  1. conc. of $\mathrm{x}$ is kept constant and conc. of $\mathrm{y}$ is halved
  2. conc. of both $\mathrm{x}$ and $\mathrm{y}$ is doubled
  3. conc. of $\mathrm{x}$ is doubled and conc. of $\mathrm{y}$ is kept constant
  4. conc. of $\mathrm{y}$ is doubled and conc. of $\mathrm{x}$ is halved

Solution

$\mathrm{r}=\mathrm{k}(\mathrm{x})(\mathrm{y})$ Of $\mathrm{x}$ is doubled and $\mathrm{y}$ remains constant the rate is doubled.
