Equilibrium 2

Question 1

partial pressure of a gas A

Answer 1

moles of gas A/total moles of gas in mixture x total pressure

Question 2

Kp

Answer 2

p(products)/p(reactants) atm

Question 3

the only effect on equilibrium constant

Answer 3

temperature not pressure and concentration

Question 4

effect of catalyst

Answer 4

increases the rates of both reactions equally so equilibrium constant remains the same and equilibrium is not shifted

Question 5

in heterogenous reactions

Answer 5

miss out the solid substances

Question 6

example why concentration has no effect on equilibrium constant

Answer 6

if conc of products decreases then top of Kp/Kc decreases but due to le chatelier the conc increases which decreases the reactants

Question 7

Kp can only be in what state

Answer 7

Gas

Question 8

Le chateliers principle

Answer 8

If a dynamic equilibrium is disturbed by changing the conditions the position of equilibrium moves to counteract the change
