WebFeb 12, 2024 · It can be found that: T = 1 kf([A]eq + [B]eq) + kr where [A]eq and [B]eq are the values at the new equilibrium at the final temperature. These value can be measured in separate experiments. Thus K, the equilibrium constant, can also be calculated from K = [C]eq [A]eq[B]eq but K = kf kr = [C]eq [A]eq[B]eq Hence, we can find kf and kr. WebThe study of chemical kinetics concerns the second and third questions—that is, the rate at which a reaction yields products and the molecular-scale means by which a reaction occurs. This chapter examines the factors that influence the rates of chemical reactions, the mechanisms by which reactions proceed, and the quantitative techniques used ...
