The graph below depicts the concentrations of four substances (A, B, C, and D) involved in a chemical reaction over the span of forty minutes in aqueous solution. From this graph, you can determine the reaction stoichiometry and with a little more information, propose mechanisms for the reaction. Rates of a Reaction 0.10 0.08 0.05 0.03 0.00 10 20 30 40 t (min) - A - B - C 1. Draw a line from the substance to 'reactant' or 'product,' which can be determined by inspecting the graph. A В Reactant Product Write the chemical reaction. D Concentration (M)
