Chem-210 Exam 1 Questions And Answers 2024

Zero order integrated rate law {Ans: [A]t = [A]0 - kt}Second order straight line plot {Ans: 1/[A] vs time}Reaction rate depends on 3 factors {Ans: 1. the concentrations of the reacting particles 2. the temperature 3. the structure and organization of the reacting particles}Molarity (M) {Ans: mol of solute/L of solution}equilibrium constant {Ans: Kc = [C]^c[D]^d/[A]^a[B]^b *only gaseous and aqueous species are included}Q=K {Ans: reaction is at equilibrium}rate-determining step {Ans: the slowest step in a reaction mechanism}saturated solution {Ans: a solution that cannot dissolve any more solute under the given conditions}Second order integrated rate law {Ans: 1/[A]t = 1/[A]0 + kt}Zero order {Ans: rate is independent of concentration}[reaction] increases/[products] decrease {Ans: reaction shifts to the right}reaction mechanism {Ans: a series of individual steps that make up a complex reaction}First order relative rate vs. concentration {Ans: when [A] doubles, reaction rate doubles}boiling point elevation {Ans: delta Tb = m*Kb}Q>K {Ans: reaction shifts left}solvent {Ans: majority component of a solution}solute {Ans: minority component of a solution}K>>1 {Ans: reaction lies to the right, product favored}K<<1 {Ans: reaction lies to the left, reactant favored}Zero order
