CHE 202 Chapter Notes - Chapter 15: Reversible Reaction, Activation Energy, Quadratic Equation
Document Summary
Revisable process: a process in which products can react to form reactants, both forward process and reverse process can occur. Example (cocl2) is a highly poisonous gas that was used on the battlefield in world war i. System not at equilibrium: qc is equal to kc only when a system is at equilibrium (qc and kc are not equal) Predicting the direction of the reaction: qc is calculated using the initial concentrations of reactants and products. To reach equilibrium, reactants must be converted to products. The system proceeds in the forward direction (from left to right): q = k, the initial concentrations are equilibrium concentrations. The system is already at equilibrium, and there will be no net reaction in either direction: q > k, the ratio of initial concentrations of products to reactants is too large. To reach equilibrium, products must be converted to reactants. The system proceeds in the reverse direction (from right to left)
