KJ Now suppose a reaction vessel is filled with 1.42 atm of nitrosyl chloride (NOCI) and 0.768 atm of nitrogen monoxide (NO) at 928. °C. Answer the following questions about this system: Is it possible to reverse this tendency adding Cl₂? In other words, if you said the pressure of NO will tend to rise, can that be changed to a tendency to fall by adding Cl₂? Similarly, if you said the pressure of NO will tend to fall, can that be changed to a tendency to rise by adding Cl₂? If you said the tendency can be reversed in the second question, calculate the minimum pressure of Cl₂ needed to reverse it. Round your answer to 2 significant digits.
