Answer 1

Suitable hypothesis for the experiment is as temperature increases rate of reaction also increases.

What is rate of reaction?

Rate of any reaction gives idea about the speed of the completion of that reaction.

Rate of reaction will be affected by many factors are some such factors are:

• Dependent variable: Rate of change of the chemical species which are present in the reaction is the dependent variables.
• Independent variable: Independent variable is temperature as it does not depends on the rate, in spite of this rate depends on temperature.
• Controlled variables: Environment of the reaction, amount of catalyst, light exposure to the reactions are the controlled variables as it depends on the requirement of the amount of product.

Hence, hypothesis is as temperature increases rate of reaction also increases.

Answer 2

Answer:

This is what I put on my test.

Explanation:

Hypothesis: as temperature increases, the rate at which chemical change occurs increases.

Dependent variable: rate of chemical change

Independent variable: Temperature

Controlled variables: light exposure, exposure to any other substance, sterile or contaminated environment
