Question
Consider the gas phase formation of ammonia gas (NH_3) from hydrogen gas (H_2) and nitrogen gas (N_2) which is conducted at 298 K. Assume the values in the table, below, are independent of temperature and pressure. (Adapted from Oxtoby 14.35) Write a balanced reaction with the product 2NH_3. Calculate the entropy change of the system for the creation of two moles of ammonia. Is the process spontaneous Justify your answer quantitatively. What is the equilibrium constant for the reaction If a rigid container is initially filled with 1 atm of NH_3(g), and no H_2(g) or N_2(g) are initially present, what are the equilibrium partial pressures for each of the three gases Approximations are not required here but are acceptable if you can provide good rationale for the approximation. Would a higher temperature shift the equilibrium towards the product (NH_3) or toward the reactants (H_2, N_2) Explain the basis for your answer, either qualitatively or quantitatively. Would a higher pressure favor the reactants or the products Justify your answer quantitatively.Explanation / Answer
