The following data were obtained for the gas phase decomposition of nitrogen dioxide at 300oC, NO2(g) NO(g) + ½ O2 Time (sec) 0.5, 10, 20, 30, NO2. Pressure(atms) 0.1, 0.0787, 0.0649, 0.0481, 0.0380. We can use pressure as a unit of concentration for a gas since we know from the ideal gas law that the pressure is directly proportional to the number of moles per unit volume.
A. Determine the order of the reaction with respect to NO2.
B. Determine the value of the rate constant (K).

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
