need the 4 stress: answered.

they all have 1 of the 3 options - say the name - products - reactants

The following stresses are applied to this reaction at equilibrium. 3H2(g)+N2(g)=2NH3(g)+heat. When the listed stress is applied, will the equilibrium shift in the direction of reactants, products, or stay the same? You will need to select the same choice more than once. Stress: the concentration of NH3 is increased Stress: a catalyst is added Stress: the reaction is placed on ice Stress: H2 is removed
