At-10.2 °C the pressure equilibrium constant K -5.5 x 10 for a certain reaction. Here are some facts about the reaction: . Some of the reactants are liquids and solids. • If the reaction is run at constant pressure, 87.0 kJ/mol of heat are absorbed. The initial rate of the reaction is 9.9 mol-L Using these facts, can you calculate X, at-17. °C? If you said yes, then enter your answer at right. Round it to 2 significant digits. Continue If you said no, can you at least decide whether K, at -17. "C will be bigger or smaller than K, at 10.2 °C? Yes.

Consider the following equilibrium: N₂(g) + 3H₂(g) 2NH, (g) AG=-34. kl Now suppose a reaction vessel is filled with 3.40 atm of hydrogen (H₂) and 8.20 atm of ammonia (NH,) at 814. "C. Answer the following questions about this system: Under these conditions, will the pressure of H₂ tend to rise or fall? Is it possible to reverse this tendency by adding N₂¹ In other words, If you said the pressure of H₂ will tend to rise, can that be changed to a tendency to fall by adding Ny? Similarly, if you said the pressure of Hy will tend to fall, can that be changed to a tendency to rise by adding N₂7 If you said the tendency can be reversed in the second question, calculate the minimum pressure of N, needed to reverse it.
