REVERSIBLE REACTIONS + EQUILIBRIUM

Question 1

What is a REVERSIBLE REACTION?

Answer 1

A reaction in which the products can react together to re-form the reactants- represented by two opposing arrows

Question 2

What is EQUILIBRIUM

Answer 2

When the rate of the forward reaction equals the rate of the reverse reaction

Question 3

INCREASING temperature

Answer 3

Increasing the temperature will shift the POE to the LEFT/RIGHT
-when temperature increases, the POE always shifts in the ENDOTHERMIC direction

Question 4

INCREASING pressure

Answer 4

Increasing pressure will shift the POE to the LEFT/RIGHT
-as the POE will shift to the side that has fewer moles of gas

Question 5

Increasing CATALYSTS

Answer 5

Using a catalyst increases the rate of reaction
-it speeds up the rate of both the forward and reverse reactions
-it does not affect the position of equilibrium
