Chemistry 132: Chapter 13 Revision Test Papers with Correct and Verified Solutions.

reaction rate - Answer -change in concentration of either a reactant or product over time -the increase in the concentration of a product per unit time or the decrease in the concentration of a reactant per unit time chemical kinetics - Answer the area of chemistry concerned with reaction rates and the sequence of steps by which reactions occur instantaneous rate - Answer the rate at a specific time during the reaction initial rate - Answer the instantaneous rate at the beginning of a reaction rate law - Answer an equation that shows how rate depends on concentration of reactants rate= k [A] ^ m [B]^n rate constant - Answer (k) the proportionality constant in a rate law reaction order - Answer (m & n) the value of the exponents of concentration terms in the rate law false - Answer A reaction's order can be determined simply by looking at the stoichiometry of the balanced chemical equation. integrated rate law - Answer expresses the reactant concentration as a function of time ln [A], time (t), negative - Answer For a first order reaction, a plot of _____ vs. _______ yields a straight line with a ________ slope. half-life - Answer (t 1/2) the time required for the reactant concentration to drop to 1/2 it's initial value
