Skill -. Recognize the order when rate = k when n = 0. 1  For a reaction that is second order with respect to a reactant A, how many times does the rate increase as [A] increases by a factor of 2.ates as Functions of Reactant Concentrations. For a second order reaction, the plot is a branch of a prabola, because. For a reaction with an infinite order, the plot is a step function. The rate is small, almost zero, when [A] less than 1.
The range of income where you stay at any particular rate is known as a tax bracket. For a single person in 2015 the rate on taxable income between $37,450 and $90,750 is 25%, so those numbers establish the 25% bracket.
