Use this equation to answer the questions:

DG=

DH-TDS.

 

= -2816-(37 x 181)

 

 

 

 

A. What happens to the probability of a spontaneous reaction occurring
a. If temperature increases, the reaction is more likely to occur.

b. If DH increases, the reaction is less likely to occur.

c. If DS increases, the reaction is more likely to occur.

 

B.
1. At 37°C, DG°' = -2892 kJ/mol

2, At 30 kJ/mol ATP, (38 ATP x 30 kJ) are required.
The free energy change is -2892-1140 = -1732.

3. The efficiency is 40%.
2872-1713 =1159
1159/2872 = 0.40
0.40 x 100 = 40%
