What happens if more reactants are added to a system at equilibrium?

Back

Equilibrium shifts to the right

Front

What happens if products are removed from a reaction at equilibrium?

Back

Equilibrium shifts to the right

Front

If heat is added to an endothermic reaction, what will happen?

Back

Equilibrium shifts to the right

Front

If heat is added to an exothermic reaction, what happens?

Back

Equilibrium shifts to the left

Front

In an exothermic reaction, which side is heat on?

Back

Product side

Front

What happens when pressure increases in a reaction with more gas moles on the left?

Back

Equilibrium shifts to the right

Front

What if a reaction has equal moles of gas on both sides and pressure changes?

Back

No shift in equilibrium
