Jon thinks about ways he could increase the rate of the chemical reaction between calcium chloride (CaCl2) and sodium bicarbonate (NaHCO3).
Which change would MOST LIKELY increase the rate of the chemical reaction?
A
use a sodium bicarbonate-water solution that has a temperature of 30°C instead of 25°C
B
use 5 grams of calcium chloride powder instead of 10 grams
C
use slow stirring instead of rapid stirring
D
use a 1000 mL beaker instead of a 500-mL beaker
Part B:
Which statement BEST explains why this change would increase the rate of the chemical reaction?
A
Molecular collisions would occur more often and with more energy.
B
Reactant and product molecules would be closer together.
C
Product molecules would have more energy and become a gas.
D
Fewer molecular collisions would be needed to form the same amount of product.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
