Effect on Equilibrium Constant

Question 5
Consider the equilibrium reaction:
NO2(g) + CO(g) ----> NO(g) + CO2(g) DHrxn = -226.4 kJ

Which one of the following factors would cause the equilibrium constant value to increase? Please explain.

a. ) Addition of a catalyst.
b. ) Removal of O2 gas.
c. ) Addition of SO2 gas.
d. ) Decrease the temperature.
e. ) All of the above

The answer is (d). The only thing that changes the equilibrium constant is temperature. I will also explain why the others don't work.

(a) addition of catalyst - a catalyst only speeds up a reaction and it only acts to bring ...

Solution Summary

The effects on equilibrium constants are determined.
