Concept introduction:
The change in reactant concentration over the course of the specified period can be viewed as the rate of a chemical reaction. According to the rate rule, the active concentration of the reactant molecules directly affects how quickly a chemical reaction proceeds. The rate constant is the name for the proportionality constant.

- ation of the reactant. When the order is negative, the rate decreases as the concentration increases. For this case, first order in CH3 CH2Br means that the reaction rate depends linearly on the concentration of CH3 CH2Br. For example, if CH3 CH2B1] is doubled, the rate doubles (increases by a factor of 2). The same is true for NaOH. Part B The reaction of ethyl bromide with sodium hydroxide, CH3 CH,Br(aq) + NaOH(aq) = CH;CH,OH(aq) + NaBr(aq) is first order in CH3 CH2Br and first order in NaOH. If the concentration of CH3 CH2Br was increased by half and the concentration of NaOH was increased by four, by what factor would the reaction rate increase?
