Which of the following ways can be used to measure reaction rate? a. measure the rate that a reactant is used up c. measure the side reactions b. measure the amount that a product is formed d. estimate the heat given off

Hi!

The correct option would be A.

The rate of reaction is described as the speed at which the conversion of substrate to product occurs.

There are two ways to measure the rate of a reaction:

1. Measure/Calculate the rate at which the product is formed.

2. Measure/Calculate the rate at which the reactant is used up.

These can be measured by observing a color change, the formation/clearance of a precipitate in the reaction vessel against time, or, for gaseous products, by attaching the vessel to a syringe to calculate the amount of gas produced per unit time.

A side reaction is a reaction that occurs simultaneously with the main reaction, and have rates that do not necessarily correspond to that of the main reaction; hence, Option C is incorrect.

The amount of heat given off indicates how exothermic a reaction is, and the rate cannot be calculated with this information; hence, Option D is incorrect.

The amount product formed or the does not indicate the rate at which a reaction takes place, but can go on to show how much of the reactants have been used; hence, Option B is incorrect.

Hope this helps!

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
