Question
(14 pts -2 pts each part, 5 min) Place a check mark in the appropriate places in the table below Consider the following system at equilibrium: A (g) + 2B (g) = 2C(s) + 4 D(g) ChangeEquilibrium Shifts No Shift Equilibrium Shifts Right to Left in Experimental Conditions Increase the pressure at Constant T Decrease the temperature at constant Left to Right Add an inert gas at constant T,V Decrease the amount B(g) at constant TV Increase the volume at constant 1 Add some C(s) at constant T,V Add a catalyst at constant T. VExplanation / Answer
According to the Le Chatelier's Principle , whenever the reaction at equillibrium is subjected to any change in reaction conditions , the equillibrium shifts in the direction where the equillibrium can be re-estabilished again.
So here :
Increase the pressure at constant T : Equillibrium shifts right to left
Decrease the temperature at constant V : Equillibrium shifts right to left
Add an inert gas at constant T , V : No shift
Decrease the amount of B (g) at constant T , V : equillibrium shifts right to left
Increase the volume at constant T : Equillibrium shifts left to right
Add some C at constant T , V : equillibrium shifts right to left
Add a catalyst at constant T , V : No shift
