Which of the following statements is correct for a spontaneous polymerization reaction?

For a spontaneous process, the incorrect statement is:

At constant pressure, the heat of formation of a compound is not dependent on temperature, when

During a reversible adiabatic process, the pressure of a gas is found to be proportional to the cube of its absolute temperature. The ratio $\frac{C_P}{C_V}$ for the gas is

The emf of a Daniel cell at 298 K is $E_{1}.\qquad$The cell is $Zn | ZnSO_{4} \left(0.01M\right)|| CuSO_{4} \left(1M\right) | CU$ When the concentration of $ZnSO_{4}$ is changed to 1M and that of $CuSO_{4}$ to 0.01M, the emf changes to E2.The relationship between $E_{1} and E_{2}$ will be

For a spontaneous process, the correct statement(s) is (are)

Pressure-volume $(PV)$ work done by an ideal gaseous system at constant volume is (where $E$ is internal energy of the system

The standard Gibbs free energy change $(\Delta G^\circ)$ at 25$^{\circ}$C for the dissociation of $N_2O_4(g)$ to $NO_2(g)$ is (given, equilibrium constant = $0.15, R = 8.314 \, J/K/mol)$

For isothermal expansion of an ideal gas, the correct combination of the thermodynamic parameters will be

Which of the following thermodynamic relation is correct ?

0.066 g of a metal was deposited when a current of 2 ampere passed for 100 seconds through an aqueous solution of its metal ion. The equivalent mass of the metal is-
