Half life equation ap chem
WebThe half-life of a reaction is the time required for a reactant to reach one-half its initial concentration or pressure. For a first-order reaction, the half-life is independent of concentration and constant over time. WebAnswer: 0.0195 mol/L. The integrated rate law for second-order reactions has the form of the equation of a straight line: 1 [ A] t = k t + 1 [ A] 0 y = m x + b. A plot of 1 [ A] t versus t for a second-order reaction is a straight line with a slope of k and a y -intercept of 1 [ A] 0.
