Expert Solution
Step 1

Reaction Rates

The pace at which a chemical reaction occurs is known as the reaction rate, which is proportional to both the increase in a product's concentration per unit time and the decrease in a reactant's concentration per unit time. There is usually a positive reaction rate. The reactant concentration is falling and there is a negative sign to show that.

 

In the given, we have some statements regarding the reaction rate out which we have to opt-out the correct statements.
