Question

How would the following changes affect the amounts of material in the system shown below initially at equilibrium.

CO (g) + 2 H2 (g) ⇄ CH3OH (l)    ΔH = –128 kJ

 

When the concentration of Hin the container is increased,

the amount of CO in the container will  (Increase, decrease, or remain the same)

 

The pressure in the container is decreased by expanding the system volume.

the amount of H2 in the container will  (Increase, decrease, or remain the same)

 

 

When CH3OH is added to the container,

the amount of CO in the container will  (Increase, decrease, or remain the same)

 

When the temperature in the container is decreased, 

the amount of CH3OH in the container will (Increase, decrease, or remain the same)

Expert Solution
Step 1

Le chatelier principal says that equilibrium will shift in such a way so as to undo the effect of change imposed. In the given question it has been asked to predict the shift of reaction.
