Consider the synthesis of ammonia: 3H2(g) + N2(g) = 2NH3(g), which has Delta H° = -92.4 kJ/mol and Delta S° = –199 J/mol at 298 K. For this problem, you may assume   all gases behave ideally.   a. Calculate Kp for this reaction.   b. If a mixture of 1.00 mol H2 and 1.00 mol of N2 is combined in a 10.0 L container and allowed to reach equilibrium, use Kp to calculate the final pressures of H2 and N2.   c. Calculate Kc for this reaction.   d. If a mixture of 1.00 mol H2 and 1.00 mol of N2 is combined in a 10.0 L container and allowed to reach equilibrium, use Kc to calculate the final concentration of H2 and N2.

Question

Consider the synthesis of ammonia: 3H2(g) + N2(g) = 2NH3(g), which has Delta H° = -92.4 kJ/mol and Delta S° = –199 J/mol at 298 K. For this problem, you may assume

 

all gases behave ideally.

 

a. Calculate Kp for this reaction.

 

b. If a mixture of 1.00 mol H2 and 1.00 mol of N2 is combined in a 10.0 L container and allowed to reach equilibrium, use Kp to calculate the final pressures of H2 and N2.

 

c. Calculate Kc for this reaction.

 

d. If a mixture of 1.00 mol H2 and 1.00 mol of N2 is combined in a 10.0 L container and allowed to reach equilibrium, use Kc to calculate the final concentration of H2 and N2.

 

e. Convert your answers from part (b) and part (d) into the same units -- how do they compare?
