Document Summary
Factors affecting reaction rate: reactant concentration, generally, the larger the concentration of reactant molecules, the faster the reaction, temperature, increasing temperature increases reaction rate, catalysts, catalysts are substances that affect the speed of a reaction without being consumed. Reaction order: exponent on each reactant in the rate law- orderwith respect to that reactant, sum of the exponents -order of the reaction. Rate = k[no]2[o2] second order with respect to [no], first order with respect to [o2], and third order overall. Reactants: change the initial concentration of one reactant at a time, effect of each reactant"s concentration on the rate determined. Comparing expt #1 and expt #2, the [no2] changes but the [co] does not. Rate law and rate constant for the reaction. Rate law and rate constant for the reactionno2(g)+ co(g) no(g)+ Integrated rate laws : zero order reactions: rate = k[a]0= k, constant rate reactions, [a] = kt + [a]initial y= mx + c straight.
