Question
For an endothermic reaction, which of the following statements is correct?Question 2AnswerA.The enthalpy change (Unknown node type: brUnknown node type: spanUnknown node type: brUnknown node type: spanB.The surroundings gain energy during the reaction.C.The system releases heat to the surroundings.D.The temperature of the surroundings decreases.
Solution
The question seems to be incomplete, but based on the given options, the correct statement for an endothermic reaction would be:
A. The enthalpy change is positive.
In an endothermic reaction, the system absorbs heat from the surroundings, which results in a positive change in enthalpy. The surroundings lose energy during the reaction, not gain, so option B is incorrect. The system does not release heat to the surroundings, it absorbs it, so option C is incorrect. The temperature of the surroundings may decrease because the system is absorbing heat, but this is not a defining characteristic of endothermic reactions, so option D is also incorrect.
