Question
c. In a different equilibrium mixture, under different conditions, the partial pressures of the
gases are shown in the table:
Gas
Partial pressure / kPa
N2
1.20 x 102
H2
1.50 x 102
NH3
1.10 x 103
Calculate the value of the equilibrium constant (Kp) for this reaction and give its units.
d. The enthalpy change for the reaction is -92 kJ mol-1
State the effect, if any, of an increase in temperature on the value of Kp for this reaction.
Explain your answer.
3. a. Name the catalyst used in the Haber process.
b. Explain why a catalyst does not change the yield of ammonia produced.
c. Sketch a Maxwell Boltzmann distribution curve (with labelled axes) and use it to explain why
a catalyst will increase the rate of reaction.
