Order of a Reaction For many (but not all) reactions with a single reactant, the rate is proportional to the concentration raised to a power. Rate expression for reaction rate = k [A] n Important: The power n has no direct relation to coefficient a in balanced reaction and must be determined experimentally. Consider the high-temperature decomposition of ethane: frequently has the form Rate expression has the form rate = k [C 2 H 6 ] 2 a A products C 2 H 6 ( g ) 2 CH 3 ( g )
