Answer:
Explanation:
The equilibrium equation is:
By LeChatelier's principle when a system in equilibrium is disturbed, the system will react to counteract the disturbance and restore fhe equiibrium.
When one of the substances increases, look at where it appears in the chemical equilibrium equation and determine how that increase can be compensated.
In this case, the system will try to balance the increase in vapor, which is on the right side of the equation, by consuming part of it and producing more water and energy through the reverse reaction, from right to left. Thus, the system will shift left.
