What is a reversible reaction?
a reaction which can take place in both directions
What is dynamic equilibrium?
when the rate of the forward reaction is qual to the rate of the backward reaction • reactants/products are equal • physical property remains constant
What effect does a catalyst have on equilibrium?
-has no effect as it increases both the forward and backward reactions
Describe the dehydration of hydrated copper sulfate
heat: blue crystals turn to white powder and water collects at top water: white turns back to blue
Describe the effect of heat on ammonium chloride
heat: decomposes it so ammonia and hydrogen chloride is formed they cool and form ammonium chloride
Effect of increasing pressure:
goes to side with fewer moles
Effect of increasing temperature:
goes in the endothermic direction
