When 1 mole of CO\(_2\) occupying volume 10L at 27°C is expanded under adiabatic condition, temperature falls to 150 K. Hence, final volume is

When $1 \,$ mole of $CO_{2(g)}$ occupying volume $10\,L$ at $27^{\circ}C$ is expanded under adiabatic condition, temperature falls to $150\, K$. Hence, final volume is

Consider the following processes \[ \Delta H (\text{kJ/mol}) = \frac{1}{2} B + 150 \] For \( B + D \rightarrow E + 2C \), \( \Delta H \) will be

The pressure exerted by 6.0g of methane gas in a 0.03m³ vessel at 129°C is (Atomic masses: C = 12.01, H = 1.01 and R = 8.314JK⁻mol⁻)

A bubble of air is underwater at temperature 15°C and the pressure 1.5 bar. If the bubble rises to the surface where the temperature is 25°C and the pressure is 1.0 bar, what will happen to the volume of the bubble?

Heat of formation, \( \Delta H_f \), of an explosive compound like NC\( _3 \) is:

For the reaction, \[ C_3H_8(g) + 5O_2(g) \rightarrow 3CO_2(g) + 4H_2O(l) \] at constant temperature, \( \Delta H = \Delta E \) is:

The favourable conditions for a spontaneous reaction are:

Two glass bulbs A and B are connected by a very small tube having a stop-cock. Bulb A has a volume of 100 cm\(^3\) and contained the gas while bulb B was empty. On opening the stop-cock, the pressure fell down to 40%. The volume of the bulb B must be:

The standard free energy change of a reaction is $\Delta G^{\circ}$ = - $115\,kJ$ at $298 \,K$. Calculate the equilibrium constant $k_p$ in $\log k_p$ $ (R = 8.314 \,Jk^{-1} mol^{-1}).$

Condition for spontaneity in an isothermal process is

Given: 2C(s) + O₂(g) \(\rightarrow\) 2CO₂(g); \[ \Delta H = -787 \, \text{kJ} \] H₂(g) + \( \frac{1}{2} \)O₂(g) \(\rightarrow\) H₂O(l); \[ \Delta H = -286 \, \text{kJ} \] C₂H₂(g) + \( \frac{5}{2} \)O₂(g) \(\rightarrow\) 2CO₂(g) + H₂O(l); \[ \Delta H = -1310 \, \text{kJ} \] The heat of formation of acetylene is
