Question

Select the statement that describes the relationship between the rate of a reaction and the length of time needed to produce a given quantity of a product of the reaction.

There is no relationship between the rate of the reaction and the time required to produce a given amount of product.

The time required to produce a given quantity of a product is inversely proportional to the rate of the reaction. For a reaction that runs twice as fast, the given quantity of product will be produced in half the time.

There is a relationship between the rate of a reaction and the time required to produce a given quantity of a product. It is not possible to know what that relationship is without running experiments.

The time required to produce a given quantity of a product is directly proportional to the rate of the reaction. For a reaction that runs twice as fast, the given quantity of product will be produced in twice the time.

Answer 1

The correct statement is that the time to produce a certain amount of product is inversely proportional to the reaction rate. In simpler terms, if a chemical reaction's rate doubles, the time to produce the same amount of product is halved.

Step-by-step explanation:

The statement that accurately describes the relationship between the rate of a reaction and the time required to produce a given quantity of a reaction product is: The time required to produce a given quantity of a product is inversely proportional to the rate of the reaction. This means that for a reaction that runs twice as fast, the given quantity of product will be produced in half the time.

Understanding the rate of reaction involves measuring how quickly reactants are converted to products over time. This can include observing changes in volume or pressure for gaseous substances, light absorption for colored substances, or conductivity for aqueous electrolytes.

The rate at which a reaction proceeds is directly influenced by the reaction conditions, such as temperature and reactant concentrations, as explained by rate laws. These laws are derived from experimental data and establish a relationship between the concentration of reactants and the speed of the reaction.

Answer 2

The time required to produce a given quantity of a product is inversely proportional to the rate of the reaction. For a reaction that runs twice as fast, the given quantity of product will be produced in half of the time.

Step-by-step explanation:

As the reaction progresses to form products, the number of successful collision decreases with increase in time and as rate increases with an increase in the collision between reactants, then time decreases.

With an increase in the system temperature, concentration, surface area and the presence of catalyst, the reaction rate increase alongside decreasing the time needed to turn reactants to products.

For instance, the presence of a catalyst in a reaction speeds up or increases the reaction rate thereby providing an alternative route or pathway to the products thereby decreasing the time of product yield and lowering the activation energy of the reaction.

Therefore as the rate increases, the time needed to convert reactants to products decreases
