Document Summary

The speed of a reaction can be affected by several factors: the nature & concentration of reactants, temperature, presence of a catalyst. The rate is the change in concentration w. r. t. time for reactants and products. (cid:858)(cid:448)e sig(cid:374) i(cid:374)di(cid:272)ates that the (cid:272)o(cid:374)(cid:272)e(cid:374)tratio(cid:374) is de(cid:272)reasi(cid:374)g. Dividing by the stoichiometric coefficient means that each value will be the same number. The concentration of reactants can affect the rate law. K is the specific rate constant at a given temperature. X and y are orders of each reactant and con only be determined experimentally (not the stoichiometric coefficients) The overall order of the reaction is x + y. The graph is linear at ln[a] vs time. [a]t = concentration of a after time t has passed. Half life = the time it takes to used up half the reactant ln 2 = 0. 693. N is the number of half-life, it does(cid:374)(cid:859)t ha(cid:448)e to (cid:271)e a (cid:449)hole (cid:374)u(cid:373)(cid:271)er. A straight line at [a] vs time.
