The order of reaction describes how much a change in the amount of each substance affects the overall rate, and the overall order of a reaction is the sum of the orders for each substance present in the reaction Reaction orders are typically first order, second order, or zero order, but fractional and even negative orders are possibleTherefore, the reaction is first order with respect to mercury(II) chloride and second order with respect to oxalate The overall order is the sum of these, 2 1 = 3, third order (b) To find the rate constant, use the rate equation and solve for k Experiment HgCl 2 (M) C 2 O 4 2– (M) Initial rate (mol L –1 min –1) k 1 0105 015 1A plot of A versus t for a zeroorder reaction is a straight line with a slope of −k and a yintercept of A 0Figure 1211 shows a plot of NH 3 versus t for the thermal decomposition of ammonia at the surface of two different heated solids The decomposition reaction exhibits firstorder behavior at a quartz (SiO 2) surface, as suggested by the exponentially decaying plot of
