Question

N2(g) + 3H2(g) 2NH3(g) ÄH = -92.4 kJ
When the reaction above took place at a temperature of 370 K, the following concentrations were measured at equilibrium:
[NH3] = 0.30 mol/L [N2] = 0.45 mol/L [N2] = 0.25 mol/l
a) Write the expression for Kc and calculate its value. (2 points)



b) Calculate Kp for the reaction (2 points)



c) Describe how the concentration of H2 at equilibrium will be affected by each of the following changes to the system at equilibrium:
i) The temperature is decreased (1 point)


ii) The pressure of the reaction chamber is decreased (1 point)


iii) N2 gas is added to the reaction chamber (1 point)


iv) A catalyst is added to the reaction chamber. (1 point)
