In comparing a reaction run under reflux versus distillation, distillation will remove the product, as it's formed. Are we using thermodynamics or kinetics to drive the reaction? Only kinetics because the raised temperature makes the reaction occur faster Only thermodynamics because we're removing products, Le Chatlier would describe this as a way to favor products OBoth kinetics and thermodynamics are favored Neither kinetics or thermodynamics are favored
