Question
  1. 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.
