Answer
Injecting a catalyst into the flask would significantly speed up the reaction without altering the equilibrium. This could explain a sudden change observed in the system.
Step 2
B. the volume of the flask was increased.

Answer
Increasing the volume of the flask would lower the pressure of gases, but it would not directly cause a sudden change that would be noticed in such a short time frame.
Step 3
C. an inert gas was injected into the flask.

Answer
Injecting an inert gas would change the total pressure but not directly affect the reaction, leading to less likelihood of a sudden change at the two-minute mark.
Step 4
D. some of the gas mixture was removed from the flask.

Answer
Removing some of the gas mixture would also change the pressure and volume in the flask, but it is less likely to cause an immediate noticeable change compared to injecting a catalyst.
