The system below was at equilibrium in a 7.0 L container. What change will occur for the system when the container is shrunk to 2.5 L? 2SO₂(g) + O₂(g) = 2SO3(g) + 198 kJ Hint: How many moles of gas are on each side? A. There is no change because there are the same number of moles of gas on both sides. B. The reactions shifts to the left (reactants) to produce more moles of gas. C. The reactions shifts to the right (products) to produce fewer moles of gas.

Consider the following equilibrium: 2NOCI (g) - 2NO (g) + Cl, (g) AG-41. kJ Now suppose a reaction vessel is filed with 4.69 atm of nitrosyl chloride (NOCI) and 4.34 atm of chlorine (CI,) at 641. "C. Answer the following questions about this system: rise Under these conditions, will the pressure of NOCI tend to rise or fall? O fall ? Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of NOCI will tend to rise, can that be changed to a tendency to fal by adding NO? Similarly, if you said the pressure of NOCI wil tend to fall, can that be changed to a tendency to rise by adding NO? O yes O no Ir you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it. Round your answer to 2 significant digits.
