• Which of the following statements about the rate of a chemical reaction is NOT true? • It is measured as a change in the amounts of reactants or products divided by the change in time. • It is defined as the negative change in concentration of products per unit time . • Typical units are M/sec, M/min. • It is defined as the negative change in concentration of reactant per unit time. 2. Below is the rate law expression for a hypothetical reaction. According to its reaction order, how does the Rate change if the concentration of A is increased by a factor of 2? Rate = k [A] • The rate stays the same. • The rate increases by a factor of 2. • The rate increases by a factor of 8. • The rate increases by a factor of 6. 3. If the plot of _______________ versus time yields a straight line, the reaction is first order. • concentration of reactant • natural log of the concentration of reactant • the reciprocal of the concentration of reactant • temperature of reactant 4. Chemical reactions that proceed at a rate that does NOT depend on the concentration of the reactant are called _______. • Zeroorder reactions • Squaredorder reactions • Firstorder reactions • Secondorder reactions 5. Below is the rate law expression for a hypothetical reaction that involves two reactants. How is the overall order for the rate law determined? m n Rate = k [A] [B] • Overall order = m – n • Overall order = m x n • Overall order = m + n • Overall order = m / n
