Chemistry - Chemical Equilibrium Question with Solution | TestHub
Which statements are correct for the illustrated system of two chambers separated by a movable insulated massless boundary? Chamber I: heat. Chamber II: heat. The external boundary is insulated.
Options:(select one or more)
Answer:
Solution:
Adding noble gas to I moves the boundary and compresses II, favouring its endothermic forward reaction with fewer gas molecules. It absorbs heat, so A is true. Removing NO₂ from II lets I expand, favouring I's endothermic reverse reaction and cooling I: B is true. Heating I compresses II; it does not provide the decrease of II's temperature needed to reduce the equilibrium constant of its endothermic forward reaction. Heating II increases that reaction's K_c. Thus the decreases claimed in C,D are not the intended effects. Answer A,B, using the source's insulating boundary and equilibrium-shift model.
