Q. What do you know about Chemical Equilibrium
Many chemical changes are reversible and will proceed towards an equilibrium instead of going to completion. The products react with themselves to produce the starting reactants all over again.
Chemical equilibrium is the dynamic state in which the rate of the forward reaction is exactly equal to the rate of the reverse reaction.
This graph illustrates that the rates of the forward and reverse reactions become equal at some point in time. When the two rates become equal, a state of chemical equilibrium has been reached.
Consider the following reaction:
NO2 + CO -> NO + CO2
The double arrow tells us that the reaction proceeds in both the forward and the reverse direction:
NO2 + CO -> NO + CO2 (forward reaction)NO + CO2 -> NO2 + CO (reverse reaction)
