In an irreversible process taking place at constant T and P and in which only pressure-volume work is being done, the change in Gibbs free energy (dG) and change in entropy (dS), satisfy the criteria

Options

  1. A( dS )_ V , E >0,( dG )_ T , P < 0
  2. B( dS )_ V : E =0,( dG )_ TPP =0
  3. C( dS )_ V , E =0,( dG )_ T , P >0
  4. D( dS )_ V , E < 0,( dG )_ T , P < 0

Correct answer

A. ( dS )_ V , E >0,( dG )_ T , P < 0

Step-by-step solution

For spontaneous reaction, d S>0 an G and dG should be negative i.e. < 0
