Question 4

Haber Process conditions for Methane + Steam —–> Hydrogen + Carbon Monoxide

Answer 4

750 *C, 30 atm, Nickel Catalyst

Question 5

Conditions for stage 2

Answer 5

gases compressed to 200 atm in compressor

Question 6

Conditions for stage 3

Answer 6

pressurised gases pumped into tank over iron catalysts at 450*C
N2(g) + 3H2(g) —> 2NH3(g)

Question 7

Conditions for stage 4

Answer 7

H2 + N2 and Ammonia pass into cooling tank

Question 8

Conditions for stage 5

Answer 8

unreacted products recycled, hydrogen and nitrogen mixed in 3:1 ratio by volume and compressed to 200 atm

Question 9

Temperature equilibrium

Answer 9

-Higher temp favours reverse reaction(more reactants)
-Low temp favours forward reaction(more products)
-Low temp also means the rate of reaction is low

Question 10

Pressure equilibrium

Answer 10

-Low atm favours reverse reaction as system, will try to increase pressure by increasing the number of molecules(more reactants)
-High atm favours forward reaction, as the system tries to decrease pressure by creating fewer molecules
-High pressure is very costly and dangerous
