- Activity: 1 Determining Reaction Orders from Rate Data PROBLEM: Many gaseous reactions occur in a car engine and exhaust system. One of these is NO (g) - CO(g) –- NO(g) + CO (g) rate = k(NOJ"(CO) Use the following data to determine the individual and overall reaction orders: Initial (NO] Initial [CO] (mol/L) Initial Rate Experiment (mol/L-s) (mol/L) 1 0.0050 0 10 0.10 0.080 0.40 0.10 0.0050 0. 10 0 20arrow_forwardThe decomposition of ammonia on a tungsten surface at 1100 °C NH3 1/2 N2 + 3/2 H2 is zero order in NH3. In one experiment, when the initial concentration of NH3 was 1.38×102 M, the concentration of NH, dropped to 3.20×103 M after 2.26x10 seconds had passed. Based on these data, the rate constant for the reaction is Ms!.
