For a first-order reaction, it takes just 101 s until exactly 10.0% of the reactant is consumed. Using the equation at the bottom of page 2.4 of the Lab Manual, calculate the rate constant, k. Note: Check your significant figures!   2. The general expression for determining the rate of a first-order reaction: Reaction: A --> B Expression:   Rate = k[A] Using this expression, determine the Rate when: k = 0.00035 s-1 [A] = 0.05273 mol L-1 Note: Round your answer to 3 significant figures.
