Question

Write a hypothesis about the effect of temperature and surface area on the rate of chemical reactions using this format: “If . . . then . . . because. . . .” Be sure to answer the lesson question, “How do the factors of temperature and surface area affect the rate of chemical reactions?”

Answer 1

Sample Response: If temperature and surface area increase, then the time it takes for sodium bicarbonate to completely dissolve will decrease, because increasing both factors increases the rate of a chemical reaction.

Answer 2

Explanation:

There are some factors that affect the rate of chemical reactions. These are as follows :

(1) Temperature  

(2) Surface area

(3) Catalyst effect

If the temperature increase, the rate of chemical reaction also increase because the particles start moving faster.

If the surface area increase, the rate if chemical reaction also increases because the chances of the collision become more. Hence, the reaction rate becomes fast.
