Question

Statement 1: Nitrogen and hydrogen combine together to form ammonia.
Statement 2: It is an exothermic reaction.

• A. Both Statement1 and Statement2 are true.
• B. Statement 1 is false and Statement 2 is true
• C. The Statement1 is true but the Statement 2 is false.
• D. Both Statement 2 and Statement 1 are false.

Answer 1

The correct option is A

Both Statement1 and Statement2 are true.

In the reaction, bonds between two atoms of nitrogen molecule and atoms of hydrogen molecules are broken and new bonds for ammonia are formed. During this process, heat energy is liberated to the surroundings. Hence this reaction is exothermic.
