Question

Which of the following circumstances will result in a reaction that is spontaneous only at low temperatures?
a. positive enthalpy change and positive entropy change
b. negative enthalpy change and negative entropy change
c. positive enthalpy change and negative entropy change
d. negative enthalpy change and positive entropy change

Answer 1

I guess it should be B

Answer 2

look at the equation: \(\Delta G=\Delta H-T\Delta S\)

A chemical reaction is spontaneous when \(\Delta G<0\)
and non-spontaneous when \(\Delta G>0\)

Answer 3

like this.. @aaronq
(delta)G = (delta)H -T(delta)S

Answer 4

So it should be B?

Answer 5

yup
