Organic reactions can often be classified into two broad categories: substitution and elimination. Substitution reactions substitute one substituent for another. Elimination reactions typically form after the wholesale removal of a substituent, with no replacement. Below are examples of two types of reactions.
Reaction 1:
Reaction 2:
1. | A scientist is studying the rate of reaction 1. He wants to double the rate of the reaction, but is unsure how to increase concentrations of the reactants. Which of the following is true? |
Reaction rate in this reaction is not determined by concentration
Doubling the concentration of the hydroxide only will quadruple the reaction rate
Doubling the concentrations of both the hydroxide and the halide will quadruple the reaction rate
Doubling the concentration of the halide only will quadruple the reaction rate
Neither doubling the concentration of halide, nor doubling the concentration of hydroxide, will quadruple the reaction rate
