It is impossible for a reaction to take place if (a) H is +ve and S is +ve (b) H is –ve and S is +ve (c) H is +ve and S is –ve (d) H is –ve and S is –ve
Answer
C
Explanation
if ∆H is positive and ∆S is negative then it will make G positive which is can’t possible for a reaction to occur Gibb’s Energy and Spontaneity
