Reversible reactions/energetics Flashcards
1
Q
What is a reversible reaction?
A
a reaction which can take place in both directions
2
Q
What is dynamic equilibrium?
A
when the rate of the forward reaction is qual to the rate of the backward reaction
- reactants/products are equal
- physical property remains constant
3
Q
What effect does a catalyst have on equilibrium?
A
-has no effect as it increases both the forward and backward reactions
4
Q
Describe the dehydration of hydrated copper sulfate
A
heat: blue crystals turn to white powder and water collects at top
water: white turns back to blue
5
Q
Describe the effect of heat on ammonium chloride
A
heat: decomposes it so ammonia and hydrogen chloride is formed
they cool and form ammonium chloride
6
Q
Effect of increasing pressure:
A
goes to side with fewer moles
7
Q
Effect of increasing temperature:
A
goes in the endothermic direction
