1 In a reaction, catalysts speed up a reaction by:
causing the reactants to collide with more kinetic energy
increasing the concentration of reactant particles
lowering the energy of the reactants and products
providing a less energetic transition state for reactants to convert to products
2Chemical equilibrium is established when:
The amount of total reactants equal the amount of total products.
The coefficients of the reactants equal the coefficients of the products.
The concentrations of all aqueous reactants equal the concentrations of all aqueous products.
The rate of the forward reaction is equal to the rate of the reverse reaction.
3A reversible reaction at equilibrium can counteract the stress of an increase in pressure by:
favoring the formation of more gaseous products
favoring the formation of fewer gaseous products
favoring the formation of more liquid products
favoring the formation of more solid products
