For an ideal gas the equation of a process for which the heat capacity of the gas varies with temperature as \( C=\alpha / T \) ( \( \alpha \) is a constant) is given by :
(a) \( V \ln T=\mathrm{constant} \)
(b) \( V T^{1 /(\gamma-1)} e^{\alpha / R T=} \) constant
(c) \( V^{\frac{1}{\gamma-1}} T e^{\alpha / R T}= \) constant
(d) \( V^{\gamma-1}=\mathrm{constant} \)
