Re: Q vs. K
K is a value for the the rate of the reaction at equilibrium. Q is a meusurement of the the rate of the reaction at any given time. But we know that the reaction will always try to attain equilibrium so the value of Q will be driven towards K. https://d2jmvrsizmvf4x.cloudfront.net/oE3LzbjfRgizQ5CQC2...
