DIRECTIONS: Read each statements carefully about the factors affecting rates of
chemical reactions are applied in food preservation and materials production, control
of fire, pollution, and corrosion. Write TRUE if the statement is correct and FALSE if
it is not

1. The presence of enzymes in food causes it to spoil quickly when left it in the dining table.

2. All enzymes can speed up the chemical reaction on material production .

3. The concentrated carbon dioxide in an extinguisher explains its fire extinguishing property .

4. Too much concentration of reacting substances causes the slow reaction rate of corrosion in metals when exposed to hydrogen .

5. Surface area of reactants could affect the reaction rate on the decomposition of waste that causes pollution .

6. The higher the temperature the faster the reaction of spoilage of foods .

7. Salting of fishes as food preservation is a result of concentrated sodium chloride to slows down the slimming process of the fish .

8. Lowering the temperature of a burning material the faster the reaction will happen .

9. When iron metal exposed to oxygen in the air it will form rust and undergo corrosion this is caused by the catalyst present on the iron metal .

10. All the factors affecting the rate of chemical reaction has a good and bad impact to the environment and human life .​
