An Ideal Gas, Consisting of N Moles, Undergoes an Irreversible

Multiple Choice

An ideal gas, consisting of n moles, undergoes an irreversible process in which the temperature has the same value at the beginning and end.If the volume changes from V_i to V_f, the change in entropy is given by:

A) n R(V_f - V_i)
B) n R ln(V_f - V_i)
C) n R ln(V_i/V_f)
D) n R ln(V_f/V_i)
E) none of the above (entropy can't be calculated for an irreversible process)
