Answer: The correct answer is (B).
Explanation:
Hypothesis is a predictive statement which relates two or more phenomena.
- It is tested to observe or to see whether it is true or false with the help of scientific means.
- it relates dependent and independent factors with each other
Theory is a tested and proved framework which explains single or multiple observed phenomena
- It is thoroughly proved and tested through experiments and observations.
- it is strongly supported by scientific evidences and observations.
Hence, a hypothesis is a prediction for a specific situation, while a theory is used to make predictions for many similar situations.
The rate expression of the change in b with time is
rb = k [b]
This is for the formation of b assuming that the reaction is first order with respect to b
For the reaction equation, the expression is
-rb = -k [b]
Again, assuming that the reaction is first order with respect to b
