For the reaction, $2Cl\left ( g \right )\rightarrow Cl_{2}\left ( g \right )$ , the correct option is :

Hydrolysis of sucrose is given by the following reaction. $Sucrose+H_{2}O\rightleftharpoons Glucose+Fructose$ If the equilibrium constant $\left ( K_{C} \right )$ is $2\times 10^{13}$ at 300 K, the value of $\Delta _{r}G^{\Theta }$ at the same temperature will be :

Other years

For irreversible expansion of an ideal gas under isothermal condition, the correct option is:

The heat of combustion of carbon to $CO_2$ is -393.5 kJ/mol. The heat released upon formation of 35.2 g of $CO_2$ from carbon and oxygen gas is:

For the reaction: $X_2O_4$ (l) $\longrightarrow$ $2XO_2$ (g), $\Delta$ U = 2.1 k cal, $\Delta$ S = 20 cal $K^{–l}$ at 300 K, Hence $\Delta$ G is
