rate equations and kp(both)

Question 1

equation for mole fraction

Answer 1

mole fraction= no. moles of gas/ total no.moles of gas

Question 2

equation for partial pressure

Answer 2

partial pressure=mole fraction x total pressure

Question 3

what effect does increase and decreasing the temperature have on kp?

Answer 3

whichever reaction is favoured, the yield of the products or reactants will increase to, increasing its partial pressures, incontrast the opposing reaction whether its reactants/products will decrease in yield decreasing its pp. in turn effecting kp depending on whether reactants or products have higher partial pressure

Question 4

what effect does adding a catalyst have on kp?

Answer 4

no effect, it will increase the rate of both the forward and backward reaction by the same amount

Question 5

what effect does changing the pressure on kp?

Answer 5

no effect. partial pressures remain the same at eqm

Question 6

what is the units of rate?

Answer 6
