Concept explainers
a)
Interpretation:Shift in equilibrium position on addition of water should be determined.
Concept introduction:Chemical equilibrium is taken into consideration if rate of forward and backward reactions become equal. At this stage, reactants and products have constant concentration. Equilibrium constant is denoted by
Le Chatelier’s principle states that if any change in conditions is done on system at equilibrium, it will result in shift of equilibrium direction in such way that tends to reduce effect of that change. These changes can be made in concentration, pressure, and temperature.
