What is a reversible reaction?
It is when products formed from a reaction can react themselves to form the reactants.
1 of 18
What is a closed system?
This is when a reversible reaction is in a closed container where no products nor reactants can escape.
2 of 18
When is equilibrium reached?
When the rate of the forward reaction and the rate of the reverse reaction is equal
3 of 18
How can we change reaction conditions including yield?
Change the temperature or pressure.
4 of 18
What happens when we change conditions at equilibrium?
The position of equilibrium will shift to oppose the change.
5 of 18
What is a exothermic reaction?
A reaction that releases heat energy as the surroundings become warmer
6 of 18
What is a endothermic reaction?
A reaction that takes in energy so the temperature of the surroundings decrease
7 of 18
What will happen if the concentration of the reactants is increased?
More products will be formed as the reaction trys to reach equilibrium
8 of 18
What will happen if a product is removed?
More reactants will react to try and reach equilibrium
9 of 18
What happens when the pressure is increased in a reaction that is at equilibrium?
The equilibrium will shift to the side of the reaction where there are fewer molecules to try and make the reaction balanced.
10 of 18
What will happen if the forward reaction produces more molecules of gas and the pressure is increased?
The yield will decrease
11 of 18
What will happen if the forward reaction produces more molecules and the pressure is decreased?
The yield will increase
12 of 18
What will happen if the forward reaction produces fewer molecules and the pressurie is increased?
The yield will increase
13 of 18
What will happen if the forward reaction produces fewer molecules and the pressure is decreased?
The yield will decrease
14 of 18
What will happen if in an exothermic reaction, the temperature is increased
The yield will decrease
15 of 18
What will happen if in an exothermic reaction, the temperature is decreased?
The yield will increase
16 of 18
What will happen in an endothermic reaction if the temperature is increased?
The yield will increase
17 of 18
What will happen in an endothermic reaction if the temperature is decreased?
The yield will decrease
