1.10 - Kp

Question 1

What is partial pressure?

Answer 1

Each gases contribution to the total pressure

Question 2

How do you calculate the partial pressure of a gas?

Answer 2

Partial pressure p = mole fraction x total pressure

Question 3

What is the mole fraction?

Answer 3

Mole fraction of gas X = number of moles of Gas-X in the mixture / by total number of moles of gas in the mixture

Question 4

What is the effect of increasing temperature on KP for an endothermic reaction?

Answer 4

Equilibrium shifts to the right, so partial pressure of products increase, so KP increases

Question 5

What will be the kinetic effect of increasing the temperature and pressure for any reaction?

Answer 5

Temp - many more particles have energy greater than or equal to the activation energy therefore more successful collisions per second

Pressure - more particles in the same volume, therefore more successful collisions per second
