Document Summary
Textbook: chemistry structure and properties by nivaldo j. tro. Low concentration of reactants: small k: rxn lies far to the left @ equilibrium, high concentration of reactants. Ex: 2n2o(g) 4no2(g) + o2(g: =[(cid:3015)(cid:3016)2](cid:3120)[(cid:3016)2] [(cid:3015)2(cid:3016)(cid:3121)]2 constant expression: the significance of the equilibrium constant. Large k (k >> 1: coefficients in the chemical equation become the exponents in the equilibrium, numerator (specifies amounts of products @ equilibrium) is larger than the denominator (specifies amounts of reactants @ equilibrium, forward rxn is favored. Equilibrium constant doesn"t say anything about how fast a rxn reaches equilibrium, only how far the rxn has proceeded once equilibrium is reached. Small k (k << 1: reverse rxn is favored, more reactants than products @ equilibrium. Equilibrium constant: @ a given temp. , the equilibrium constant has only 1 value & it specifies the relative amounts of reactants & products at equilibrium.
