Question

I know how the signs change from the table delta G= delta H-tdelta S

1 + + -

2 - - +

3 temp high + - -

4 temp low - - -

5 temp high - + +

6 temp low + + +

I know in the reverse direction and high temp. it will be non spon. and two possibilities : delta G =+, delta H= - , delta s= - or delta g + , delta H= + , delta s= -, #3 and 2. but i cant figure out how to relate it to the three reactions given at 25c explain and thanks

14). The signs of AG, AH, and AS at 25°C are shown below for three reactions (4p reaction AG H aS I. Which reaction could go in the reverse direction at high temperature? (must show work) t and I E) None of the above 15). A reaction has ,+40.9 kl Inol and AS-266 h 1 K 1 te men

Explanation / Answer

For a reaction to be spontaneous the delta G should be negative.For all the three given reactions the deltaG is negative.This mens all reaction are spontaneous.No any reaction will go in reverse direction.
