kPa

Question 3

State what is meant by the term ‘partial pressure’

Answer 3

The pressure a gas would exert if it occupied the container alone

Question 4

How do you work out the mole fraction (Xa)?

Answer 4

Xa = no. moles of gas A/total no. of moles of gas

Question 5

How do you work out the partial pressure of a gas (Px)?

Answer 5

Px = mole fraction of X x total pressure

Question 6

State what is meant by the rate determining step

Answer 6

The slowest step, which defines how fast a reaction is
