Just made it a new post didn't what it to get overcrowning.I hope this will help us figure out now


For questions #1 through #10, refer to the following equilibrium system, with a Kc of 1.23E-03:

C3H6O (aq) + 2C2H6O(aq)----> C7H16O2 (aq) + 2H2O (l)

1. What is the equilibrium expression for this system?
[C7H16O2]/ [C3H6O][C2H6O]2

2.If the molar concentrations of C3H6O2 and C2H6O are both 0.255 at equilibrium, what is the equilibrium concentration of C7H16O2?
2.04E-06

3.What is true about the concentrations of the reactants and products at equilibrium?

The reactant concentrations are increasing, while the products are decreasing

4.What is true about the rate of the forward and reverse reactions at equilibrium?
They are identical

5.Is this an endothermic- or exothermic reaction, as written?
Exothermic


6.How would the equilibrium shift if the pressure of the system were doubled?
To the left

7.How would the equilibrium shift if C7H16O2 were added?
To the right

8.How would the equilibrium shift if the system were cooled?
No change

9.What would the Kc be for the reverse equilibrium? That is, for:

C7H16O2 (aq) + 2H2O (l)---> C3H6O (aq) + 2C2H6O (aq)

813

10.For the reverse equilibrium, as depicted in #9, is this an endo- or exothermic process?
endothermic
