Reversible reactions 0.0 / 5 ? ChemistryReversible reactionsGCSEAQA Created by: emewsCreated on: 22-11-17 15:51 What happens at equilibrium? At equilibrium, the concentrations of reactants and products do not change. But they still react at the same rate as each other. 1 of 7 What happens to the position of the equilibrium if the temperature is increased? If the temp is increased the position of equilibrium moves in the direction of the endothermic reaction. 2 of 7 What happens to the position of the equilibrium if the temperature is decreased? If the temp is decreased the position of equilibrium moves in the direction of the exothermic reaction. 3 of 7 What happens to the position of the equilibrium if the pressure is increased? If the pressure is increased, the position of the equilibrium moves in the direction of the fewest moles of gas. 4 of 7 What is a closed system? A chemical reaction in a container where none of the reactants or products can escape. 5 of 7 What is an open system? A chemical reaction in a container where one or more of the reactants or products can escape. 6 of 7 How do you write the arrow in a reversible reaction equation? The top arrow points right and the left arrow points left. 7 of 7
