Chapter 15 Kinetics

DEFINE:

• Rate of a reaction in terms of rate of loss of reactants or rate of formation of products given the balanced chemical reaction
• The factors (concentration & temperature) that affect the rate of reactions
• Catalyst and its effect on rate
• Rate determining step

DO:

• Determine the instantaneous rate law of a reaction from a graph of concentration vs time
• Write rate laws for first-order, zero-order and second-order reactions
• Interpret reaction profile (energy vs. reaction progress) graphs to find the activation energy(E_a) of forward and reverse reactions
• Evaluate plausibility of proposed mechanism
• Identify reaction intermediates
• Determine rate laws and rate constants from graphs of [A] vs time, ln [A] vs time, and [A]^-1 vs time

CALCULATE:

• Rate constant (k) and the rate law from concentration and initial rate data
• Rate order from a rate law
• Concentration of reactant at a given time from integrated rate law
• Concentration of reactant at a given time from half-life
• New rate constant at a new temperature from original rate constant and temperature
• Activation energy(E_a) of a reaction from rates and temperature data (Arrhenius equation) or graphs of ln k versus 1/T
