Which of the following statements are true of the malate dehydrogenase reaction in biochemical standard conditions?  Choose all that apply. Group of answer choices:   The reaction is spontaneous since ∆G°' is positive The reaction is spontaneous since ∆G°' is negative The reaction is not spontaneous since ∆G°' is positive The reaction is not spontaneous since ∆G°' is positive The equilibrium favors products since K is greater than 1 The equilibrium favors reactants since K is greater than 1 The equilibrium favors products since K is less than 1 The equilibrium favors reactants since K is less than 1 The reaction is always at equilibrium       B)  If the concentration of oxaloacetate is 107 times lower than the concentration of malate.  Is the reaction spontaneous?  Assume biochemical standard conditions. Group of answer choices No, because RTlnQ is very positive Yes, because RTlnQ is very positive No, because RTlnQ is very negative Yes, because RTlnQ is very negative No, because RTlnQ is equal to ∆G°' Not enough information

Question

Hello,

For the image included:

A)

Which of the following statements are true of the malate dehydrogenase reaction in biochemical standard conditions?  Choose all that apply.

Group of answer choices:
 
The reaction is spontaneous since ∆G°' is positive
The reaction is spontaneous since ∆G°' is negative
The reaction is not spontaneous since ∆G°' is positive
The reaction is not spontaneous since ∆G°' is positive
The equilibrium favors products since K is greater than 1
The equilibrium favors reactants since K is greater than 1
The equilibrium favors products since K is less than 1
The equilibrium favors reactants since K is less than 1
The reaction is always at equilibrium
 
 
 
B) 
If the concentration of oxaloacetate is 107 times lower than the concentration of malate.  Is the reaction spontaneous?  Assume biochemical standard conditions.
Group of answer choices
No, because RTlnQ is very positive
Yes, because RTlnQ is very positive
No, because RTlnQ is very negative
Yes, because RTlnQ is very negative
No, because RTlnQ is equal to ∆G°'
Not enough information
 
(I know two of the choices are not "No because RTIn is very positive"  or "No because RTIn is very negative", I had selected those and got it incorrect.)
