Learning Goal:To understand zero-order reactions.Chemical kinetics is the study of the speed with which a chemical reaction occurs and thefactors that affect this speed. The speed of a reaction is the rate at which theconcentrations of reactants and products change. This relationship is expressed throughrate laws.For a general reaction aA + bBgG+ hH, the rate law is given asrate of reaction= k[A] [B]"where the coefficients and are experimentally determined while a, b, g, and h arestoichiometric coefficients unrelated to me and nAzero-order reaction has a rate law in which the sum of the exponents m +n + ... isequal to zero. Thus, if there is only one reactant, the rate of reaction is independent of theconcentration of the reactant.For a zero-order reaction, the graph of reactant concentration versus time is a straight line.Therefore, the rate-law equation for a zero-order reaction can be compared to that of astraight line, y = mz+b✓ CorrectImportant: If you use this answer in later parts, use the full unrounded value in your calculations.The faster the reaction, the shorter the half-life for that reaction. The rate of the reaction is proportional to rate constant; thus, the larger the rate constant, the shorter the half-life.Part DIn a certain hypothetical experiment, the initial concentration of the reactant R is 1.00 mol-L, and its rate constant is 0.0150 mol-Ls. It follows a zero-order reaction mechanism for the consumption ofreactant R. Plot the graph of concentration versus time.
