Answer:
The forward reaction rate increases.
Step-by-step explanation:
Consider the following reaction.
Chemical reaction:
A + B ⇄ C + D
In this reaction the equilibrium is disturb by increasing the concentration of reactant B.
When the concentration of reactant B is increased the system will proceed in forward direction in order to regain the equilibrium. Because when reactant concentration is high it means reaction is not on equilibrium state. As the concentration of B increased the reaction proceed in forward direction to regain the equilibrium state.
According to the Le- Chatelier principle,
At equilibrium state when stress is applied to the system, the system will behave in such a way to nullify the stress.
The equilibrium can be disturb,
By changing the concentration
By changing the volume
By changing the pressure
By changing the temperature
