A gas obeying the equation of state PV = RT undergoes a hypothetical reversible process described by the equation, `PV^(5//3)"exp"(-(PV)/(E_(0)))= c_(1 )` where `c_(1)` and `E_(0)` are dimensioned constants. Then, for this process, the thermal compressibility at high temperature
A. approaches a constant value.
B. is proportional to T.
C. is proportional to `T^(1//2)`
D. is proportional to `T^(2)`.
