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!

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
