​ Which of the following is not correct? (1) △G is negative for a spontaneous reaction (2) △G is positive for a spontaneous reaction ​

Question

Which of the following is not correct? 

(1) \(\triangle\)G is negative for a spontaneous reaction 

(2) \(\triangle\)G is positive for a spontaneous reaction 

(3) \(\triangle\)G is zero for a reversible reaction 

(4) \(\triangle\)G is positive for a non-spontaneous reaction

Answer 1

(2) \(\triangle\)G is positive for a spontaneous reaction

\((\triangle G)_{P,T}=(+)\) ve for non-spontaneous process.
