The value of $$\triangle G$$ for the process $$H_{2}O(s) \rightarrow H_{2}O(l)$$ at $$1\ atm$$ and $$260\ K$$ is:-

The reaction $$NH_{2}CN(s) + \dfrac {3}{2}O_{2}(g) \rightarrow N_{2}(g) + CO_{2}(g) + H_{2}O(l)$$ was carried out at $$300\ k$$ in a bomb calorimeter. The heat released was $$742\ kJ\ mol^{-1}$$. The value of $$\triangle H_{300K}$$ for this reaction would be_________.

Following reaction occurs at $${25}^{o}C$$:
$$2NO(g, 1\times { 10 }^{ -5 }atm)+{ Cl }_{ 2 }(g, 1\times { 10 }^{ -2 }atm)\rightleftharpoons 2NOCl\ \left( g, 1\times { 10 }^{ -2 }atm \right) $$
$$\Delta { G }^{ o }$$ is_______________.

$$100ml$$ of $${O}_{2}$$ gas diffuses in $$10$$ seconds. $$100ml$$ of gas $$x$$ diffuses in $$t$$ seconds. Gas $$x$$ and time $$t$$ can be respectively:

When two moles of Hydrogen atoms join together to form a mole of hydrogen molecules in closed rigid vessel with diathermic walls:
$$H(g)+H(g)\longrightarrow { H }_{ 2 }(g)$$

The difference between the heat of reaction at constant pressure and constant volume for the reaction given below at $${25}^{o}C$$ in KJ is: 

The normal boiling point of a liquid A is 350 K. $$\Delta { H }_{ vap }$$ at normal boiling point is 35 KJ/mole. Pick out the correct statement(s). (Assume $$\Delta { H }_{ vap }$$ to be independent of pressure).

Given standard enthalpy of formation of $$CO$$ (-110 KJ $${ mol }^{ -1 }$$) and $$C { O }_{ 2 }$$ (-394 KJ $${ mol }^{ -1 }$$ ). The heat of combustion when one mole of graphite burns is:

For the reaction, $${ X }_{ 2 }{ O }_{ 4 }\left( l \right) \longrightarrow 2X{ O }_{ 2 }\left( g \right)$$
$$\Delta U=2.1\ k\ cal$$, $$\Delta S=20\ cal\ { K }^{ -1 }$$ at 300 K Hence , $$\Delta G$$ is_________.

The heat liberated on complete combustion of 1 mole of $${ CH }_{ 4 }$$ gas to $${ CO }_{ 2 }\left( g \right)$$ and $${ HO }_{ 2 }\left( l \right)$$ is 890 KJ. Calculate the heat evolved by 2.4 L of $${ CH }_{ 4 }$$ on complete combustion.
