Consider the following equilibrium: 2NO g +Cl2 g 2NOCl g ΔG0=−41.kJ Now suppose a reaction vessel is filled with 0.258 atm of chlorine Cl2 and 8.51 atm of nitrosyl chloride NOCl at 508. °C. Answer the following questions about the system: Under these conditions, will the pressure of Cl2 tend to: rise or fall? Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of Cl2 will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of Cl2 will tend to fall, can that be changed to a tendency to rise by adding  YES OR NO? If 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. = ? atm

Question

Consider the following equilibrium:

2NO g +Cl2 g 2NOCl g ΔG0=−41.kJ
Now suppose a reaction vessel is filled with 0.258 atm of chlorine Cl2 and 8.51 atm of nitrosyl chloride NOCl at 508. °C. Answer the following questions about the system:

  • Under these conditions, will the pressure of Cl2 tend to: rise or fall?
  • Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of Cl2 will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of Cl2 will tend to fall, can that be changed to a tendency to rise by adding  YES OR NO?
  • If 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. = ? atm
