" If a system at equilibrium is disturbed, the system shifts to counter
the effect of the disturbance"
Pressure and Le Chatelier's Principle
count the number of gas molecules on each side of the balanced chemical equation.
* a shift towards more gas molecules INCREASES pressure.
*a shift towards fewer gas molecules DECREASES pressure.
remember: if the numbers of gas molecules is equal, then changes in pressure has no effect.
