Question

Consider the combustion of methane (as represented by the following equation). This is the reaction that occurs for a Bunsen burner, which is a source of heat for chemical reactions in the laboratory.   

CH 4( g) + 2O 2( g)     CO 2( g) + 2H 2O( g)

For the system at chemical equilibrium, which of the following explains what happens if the temperature is reduced?

a.

The equilibrium position is shifted to the right and the value for K decreases.

b.

The equilibrium position is shifted to the left and the value for K increases.

c.

The equilibrium position is shifted to the right and the value for K increases.

d.

The equilibrium position is shifted but the value for K stays constant.

e.

The equilibrium position is shifted to the left and the value for K decreases.
