Someone Help Me Please !!!



For a certain reaction, the change in Enthalpy is negative and the change in
Entropy is positive at a temperature of 300K: AH <0, and TAS > 0. (1pt ea)
a) Is AG = AH - TAS positive or negative?
b) Is it a spontaneous reaction or not?

Answer 1

Answer:

a) ◇G = ◇H - T◇S wiĺl be negative.

b) It will be a spontaneous reaction.

Explanation:

As ◇H is less than 0 and T◇S is greater than 0 so if we put it in the equation we would get the negative maximum result. And when the energies are with negative sign they are said to be spontaneous.
