20 mL of H2S is burnt in excess O2 according to 2H2S + 3O2 -> 2SO2 + 2H2O. After cooling to room temperature, the volumes of SO2 formed and O2 consumed are respectively

JEE Main levelSingle correct optionDifficulty 2 of 3ig188

$20 mL$ of $H X_{2} S$ is burnt in excess $O X_{2}$ according to $2 H X_{2} S + 3 O X_{2} 2 SO X_{2} + 2 H X_{2} O$ . After cooling to room temperature, the volumes of $SO X_{2}$ formed and $O X_{2}$ consumed are respectively

Volume ratios follow the equation:

2 : 3 : 2

20 mL

H X_{2} S

gives

20 mL

SO X_{2}

and uses

30 mL

O X_{2}
