Final answer:
When the concentration of [K]in is changed to 150mM, the equilibrium constant (EK) will increase.
Step-by-step explanation:
When the concentration of [K]in is changed to 150mM, the equilibrium constant (EK) will also change. The equilibrium constant is a measure of how far a reaction proceeds towards the formation of products. If the concentration of reactants is decreased, the equilibrium constant will increase, indicating that the reaction is more favorable in the forward direction.
For example, if the initial concentration of [K]in is 0.15M and it is changed to 150mM, the equilibrium constant (EK) would increase. The exact value of the new equilibrium constant cannot be determined without additional information about the reaction.
In summary, when the concentration of [K]in is changed to 150mM, the equilibrium constant (EK) will increase.
