Reaction Rates
Let's talk about Molarity
Molarity Calculations
100
What happens to the reaction rate as you decrease the temperature of the reaction?
Rate decreases
100
What's the molarity equation?
M = mol solute/L solution

I want my food to digest faster, so I am sure to chew it up thoroughly.
Does chewing food increase its surface area or decrease its surface area?
Increase the surface area
200
Does increasing the molarity make a solution more concentrated or more dilute?
More concentrated
200
What is the molarity of a solution with 0.32 moles of solute and 560 mL of solution?
0.57 M
