Kinetics and energetics

Question 1

what is a dynamic equilibrium

Answer 1

rate of forward reaction is equal to rate of the reverse reaction

Question 2

what is a closed system

Answer 2

temperature, pressure and concentrations is unaffected by outside influences

Question 3

what is Le Chateliers principle

Answer 3

when an equilibrium is subjected to external change the system readjusts itself to minimise effects

Question 4

what is the effect of increasing temperature
- Le Chateliers principle

Answer 4

equilibrium shifts to endothermic direction

Question 5

what is the effect of decreasing temperature
- Le Chateliers principle

Answer 5

decreasing pressure favours the exothermic direction

Question 6

what is effect of increasing pressure
- Le Chateliers principle

Answer 6

shifts equilibrium to the side with fewer number of moles

Question 7

what is the effect of decreasing pressure
- Le Chateliers principle

Answer 7

shifts equilibrium to side with the most moles

Question 8

what is the effect of a catalyst

Answer 8

speeds up rate of forward and reverse reaction
