10) Consider the following reaction at equilibrium. What effect will increasing the temperature have on the system? Fe3O4 (s) + CO(g) = 3 FeO(s) + CO28) AH°= +35.9 kJ A) No effect will be observed. B) The reaction will shift to the right in the direction of products. C) The equilibrium constant will increase. D) The reaction will shift to the left in the direction of reactants. E) The equilibrium constant will decrease.

1. For the reaction: 2NH3(g) + CO2(g) (NH2)2CO(s) + H2O(g) AH = - 330 kJ Predict how each of the following changes would impact a reaction that is currently at equilibrium. That is, which way would the reaction progress in order to respond to the change in the system to regain equilibrium (use arrows to show the direction of change that would occur to return back to equilibrium). Explain your reasoning for each part.

Please answer ALL parts of the question and show your work. Consider this reaction: 2H2S(g) + 3O2(g)  <-----> 2H2O(g) + 2SO2(g)       H= -1036 kJ Predict whether the forward or reverse reaction will reestablish equilibrium is disturbed by (a) expanding the container (b) removing SO2 (c) rasing the temperature (d) water vapor is added

Can you provide an explanation? And show the steps

Consider the system N2(g) + 3 Cl2(g) 2 NCI3(g) AH = +232 kJ Predict whether the forward or reverse reaction will occur when the equilibrium is disturbed by each of the following. decreasing the temperature removing nitrogen trichloride gas 1. forward reaction compressing the system at constant temperature 2. reverse reaction adding chlorine gas

Which way would the equilibrium shift if the temperature was decreased for this reaction (AH = -542 kJ)? H₂ (g) + F₂ (g) → 2HF (g) Shift toward reactants Shift toward products Remain the same None of the above

Consider the following exothermic reaction, used to obtain lead from its ore:2PbS (s) + 3O2 (g) + 2CO (g) ↔ 2 Pb (l) + 2SO2 (g) + 2CO2 (g)Assume that this reaction is in equilibrium. Given the following changes to the system, will the quantity of lead increase, decrease, or remain the same?i) adding more lead sulfide.ii) Adding more carbon monoxide.iii) removing some oxygen.

Consider the following equilibrium: 2NO, (g)–N,04 (8) AGº= – = - 5.4 kJ Now suppose a reaction vessel is filled with 5.06 atm of dinitrogen tetroxide (N,0) at 400. °C. Answer the following questions about this system: 2 rise Under these conditions, will the pressure of N,0, tend to rise or fall? 2 4 fall Is it possible to reverse this tendency by adding NO,? In other words, if you said the pressure of N,0, will tend to rise, can yes that be changed to a tendency to fall by adding NO,? Similarly, if you no said the pres of N,0, will tend to fall, can that be changed to a 2 4 tendency to rise by adding NO,? If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO, needed to reverse it. atm Round your answer to 2 significant digits.
