A reaction is second-order with respect to reactant A. The graph below shows the inverse concentration of A (in L/mol, or inverse of molarity) versus time of reaction. Use the graph to determine the rate constant for the reaction and the initial concentration of reactant A in the reaction. (Give your answers to two significant figures because the x and y values are limited to two significant figures.) The rate constant (k) is ________ M$^{-1}$s$^{-1}$ and the initial concentration of reactant A is ________ M. 14.0 12.0 10.0 8.0 1/[A] (L/mol) 6.0 4.0 2.0 0.0 0.0 4.0 8.0 12.0 16.0 20.0 24.0 time (s)
