Ammonia is an important ingredient in many fertilizers. The main process by which ammonia is made is the Haber process. In this process, nitrogen gas and hydrogen gas are reacted to form ammonia at high temperatures. Which of the following most likely explains why this reaction is carried out at high temperature?Ammonia is unstable at room temperature.
High temperatures increase the activation energy of the reaction.
High temperatures make the gas molecules move more quickly.
The reaction becomes exothermic at high temperatures.

Answers

Answer 1

Answer: The best answer is "High temperatures increase the activation energy of the reaction."

The Haber process is an exothermic reaction at room temperature. This means that the reaction actually favors the reverse reaction, especially when the temperature is increased. So why increase the reaction temperature?

The reason for this is that nitrogen is a very stable element. Therefore, more energy is needed to overcome the slow rate of reaction. So the reaction temperature must be low enough to favor a forward reaction, but high enough to speed up the reaction.

What is a single kind of matter that is pure, having a specific makeup and specific properties? a) Element b) Compound c) Mixture d) Substance

Answers

Answer:

Element

Explanation:

Final answer:

A Substance, either an element or compound, is a single kind of matter that is pure, having a consistent makeup and specific properties. Elements consist of a single type of atom while compounds consist of two or more types of atoms.

Explanation:

The single kind of matter that is pure, having a specific makeup and specific properties is termed as a Substance. A substance can be classified as an element or a compound. Elements consist of only one type of atom and cannot be broken down by a chemical change. On the other hand, compounds consist of two or more types of atoms. It's essential to note that both elements and compounds have a constant composition from point to point, but mixtures don't necessarily maintain the same composition throughout.
