Questions in this quiz (6)
1What effect does increasing the pressure of a closed gaseous system at equilibrium have on the state of equilibrium if the forward reaction creates 2 mol and the reverse reaction creates 3 mol?
- ANo effect
- BThe forward reaction becomes favored
- CThe reverse reaction becomes favored
2The addition of a catalyst to a system at equilibrium will increase the concentration of the products of the forward reaction.
- ATrue
- BFalse
3An increase in temperature will do what to a system at equilibrium?
- AShift the equilibrium to favor the endothermic reaction.
- BChange the Kc value (equilibrium constant)
- CIncrease the concentration of products produced by the endothermic reaction
- DAll of the above
4An increase in the concentration of the products results in an increase in the value of Kc
- ATrue
- BFalse
5Le Chatelier's principle states that when stress is placed on a system at equilibrium the system will work in such a way that reduces this stress.
- ATrue
- BFalse
6Increasing the concentration of A will do what to the following system at equilibrium?
A + B <-----> C + D- AThe system will shift to favor the reverse reaction so that the concentration of B will become equal to A
- BThe system will shift to favor the forward reaction to reduce the increase in concentration of A
- CThe system will not be affected
- DThe Kc constant will decrease
