Yogesh C Sharma

Renu,

If you mean that its negative value is decreasing, it means that the process is becoming more feasible at elevated temperatures!

Renu Bisht

Sir,

Delta G is at 18 C = -9.719 KJ/mol, 35 C= -7.963 KJ/mol and 53 C = - 4.015 KJ/mol and the obtained values of enthalpy and entropy both are negative. How i can explain this condition.?

Thank you

I could see the data, it indicates that spontaneity of the reaction decreases with increasing temp.

Best,

Thanks a lot.
