Question

EXPERIMENT 14 Pre-Lab Questions 1. You need to take a medicine orally and want quick action. The medicine is available in the form of a compressed tablet or as a loose powder. Which form would give you the desired quick action? Why? 2. Some reactions require an additional chemical in a non-stoichiometric amount in order to catalyze the reaction. How does a catalyst promote a reaction? 3. Below is an equation that describes the rate of reaction between reagents A and B: A + B \rightarrow C Rate = k \times [A] \times [B] where k is a constant, [A] is the concentration of A in moles per liter, and [B] is the concentration of B in moles per liter. a. What happens to the reaction rate if the concentration of A is doubled? b. What happens to the reaction rate if the concentration of B is doubled? c. What happens to the reaction rate if the concentrations of both A and B are doubled?

Pre-Lab Questions
1. You need to take a medicine orally and want quick action. The medicine is available in the form of a
compressed tablet or as a loose powder. Which form would give you the desired quick action? Why?
2. Some reactions require an additional chemical in a non-stoichiometric amount in order to catalyze
the reaction. How does a catalyst promote a reaction?
3. Below is an equation that describes the rate of reaction between reagents A and B:
A + B \rightarrow C
Rate = k \times [A] \times [B]
where k is a constant, [A] is the concentration of A in moles per liter, and [B] is the concentration of B
in moles per liter.
a. What happens to the reaction rate if the concentration of A is doubled?
b. What happens to the reaction rate if the concentration of B is doubled?
c. What happens to the reaction rate if the concentrations of both A and B are doubled?

3. Below is an equation that describes the rate of reaction between reagents A and B:
A + B →C
Rate = k ×[A] ×[B]
where k is a constant, [A] is the concentration of A in moles per liter, and [B] is the concentration of B
in moles per liter.
a. What happens to the reaction rate if the concentration of A is doubled?
b. What happens to the reaction rate if the concentration of B is doubled?
c. What happens to the reaction rate if the concentrations of both A and B are doubled?
