Two moles of a monoatomic gas in state ‘A’ having critical pressure `P_0` and temperature `3T_0` is taken to a state B having pressure 3P, and temperature `T_0//3` by the process of equation `P^2T` = constant. Then, state B is taken to state C keeping volume constant and comes back to initial state ‘A’ keeping temperature constant. Heat supplied to the gas during complete cycle is cycle is `RT_0 [(18 logx) – 8]` . Determine the value of .x..
