A reversible reaction is one in which both the forward and reactions can take place.
|
Which of the following statements about a system in equilibrium are true?
(Select all that apply)
It requires a closed system
The forward and backward reactions occur at the same rate
The concentrations of the reactants and products remain constant
The concentrations of the reactants and products are equal to each other
|
To reach equilibrium, the reactants and products must be in a system. This means that the reactants and products can't escape.
|
At equilibrium, if the concentration of reactants is higher than the concentration of products, we say that the position of equilibrium lies to the:
Left
Right
|
What happens in an endothermic reaction?
Heat energy is given out to the surroundings
Heat energy is taken in from the surroundings
|
In a reversible reaction, if the forward reaction is exothermic, the backward reaction is .
|
If the position of equilibrium lies to the right, it means there are more:
Reactants
Products
|
In a reversible reaction, if the forward reaction is endothermic, what would be the affect of increasing the temperature?
Equilibrium would shift to the left
Equilibrium would not shift
Equilibrium would shift to the right
|
In a reversible reaction, if the forward reaction is exothermic, what would be the effect of decreasing the temperature?
No change in the yield of products
Yield of products would decrease
Yield of products would increase
