The chemical reaction between hcl(aq)hcl(aq) and nh3(aq)nh3(aq) is represented above. a student combines equimolar amounts of hcl(aq)hcl(aq) and nh3(aq)nh3(aq), both solutions initially at 24°c24°c, in a coffee-cup calorimeter. the student observes that the mixture reaches a temperature of 28°c28°c. based on the experimental results, which of the following can be concluded about the reaction?

it is an endothermic process, because energy is released by the reaction and is gained by the reaction mixture.

a

it is an endothermic process, because energy is absorbed by the reaction and is lost from the reaction mixture.

b

it is an exothermic process, because energy is released by the reaction and is gained by the reaction mixture.

c

it is an exothermic process, because energy is absorbed by the reaction and is lost from the reaction mixture.

The reaction has been termed an exothermic reaction as energy is released by the reaction and gained by the reaction mixture. Thus, option C is correct.

The reaction can be classified as exothermic and endothermic reactions based on the energy that has been absorbed or released.

When the energy is absorbed by the system from the surrounding, the reaction has been termed an endothemic reaction. This type of reaction decreases the temperature of the solution.

The reactions in which the energy has been released by the reaction mixture have been termed an exothermic reaction. In these reactions, there has been increase in the temperature of the reaction mixture.

In the given reaction, the reaction mixture temperature has been raised. Thus the reaction has been termed an exothermic reaction as energy is released by the reaction and gained by the reaction mixture. Thus, option C is correct.

The answer is: It is an exothermic process, because energy is released by the reaction and is gained by the reaction mixture.

Explanation:

Endothermic (endo means in, inside; thermic refers to temperature) reaction is a type of reaction which needs to absorb the energy in order to take place. The energy in the form of the temperature is lost from the reaction mixture.

Exothermic (exo means out, outside; thermic refers to temperature) reaction is a type of reaction in which the energy in form of the temperature is being released.

Since we know that the temperature rose from 24°C to 28°C, that means that the energy was released making this process exothermic.
