Suppose it takes 35 min for 1.7 g of sugar to completely react with another reagent we added to the flask. what would the reaction rate be?

The rate of the reaction can be calculated using the following rule:

rate of reaction = mass / time

For this problem, we have 1.7 grams of sugar reacting in 35 minutes.

Based on this:

rate of reaction = 1.7 / 35 grams/minute

Although we should note that the rate of the chemical would be faster in the beginning of the reaction than in the last minute of the reaction.
