Answer 1

b - the reaction container is cold

Step-by-step explanation:

Answer 2

Answer: The correct option is - The reaction container is cold.

Explanation: Endothermic reaction is a reaction in which the system absorbs energy from the surroundings, generally in the form of heat.

In this process, the surrounding becomes cold after loosing energy.

And here, the surrounding is reaction container and hence, will become cold by loosing its energy to the reaction mixture.
