Input (English): The Curtin-Hammett principle states that product ratios are based on transition state ratios and not this conformation value. The rate constant is related to this value by the Brnsted relation and its temperature dependence is given by the (*) van't Hoff equation. It can be obtained from activities through the law of mass action. The natural logarithm of this value times the gas constant and temperature yields the standard Gibbs energy change of a reaction. For 10 points, name this constant that changes according to Le Chatelier's principle.
Output (English): Science
