Question
How does Gibbs free energy indicate a reaction is spontaneous at high temperatures? Remember: delta G = delta H - T (delta S)?
The value of the entropy change and temperature product together overwhelms the positive value of the enthalpy change when they are added to it.
The value of the negative entropy change and temperature product together overwhelms the positive value of the enthalpy change when they are subtracted from it.
The value of the negative entropy change and temperature product together overwhelms the positive value of the enthalpy change when they are added to it.
The value of the entropy change and temperature product together overwhelms the positive value of the enthalpy change when they are subtracted from it.
a)The value of the entropy change and temperature product together overwhelms the positive value of the enthalpy change when they are added to it.
b)The value of the negative entropy change and temperature product together overwhelms the positive value of the enthalpy change when they are subtracted from it.
c)The value of the negative entropy change and temperature product together overwhelms the positive value of the enthalpy change when they are added to it.
d)The value of the entropy change and temperature product together overwhelms the positive value of the enthalpy change when they are subtracted from it.
Explanation / Answer
d) The value of the entropy change and temperature product together overwhelms the positive value of the enthalpy change when they are subtracted from it.
delta G = delta H - T (delta S)
T (delta S)>delta H at high temprature making whole term -ve
