which of the following statements is true?\no the overall chemical reaction is exothermic.\no there are two intermediate reactions in this system.\no the third intermediate reaction is endothermic.\no the longest arrow represents the overall chemical reaction.
Answer
Explanation:
Step1: Analyze exothermic/endothermic
Since $\Delta H_{rxn}$ is downward - pointing, heat is released. An exothermic reaction releases heat.
Step2: Analyze intermediate reactions
The diagram doesn't clearly show the number of intermediate reactions from the given information.
Step3: Analyze third intermediate reaction
There is no clear indication that the third intermediate reaction is endothermic.
Step4: Analyze arrow length
There is no information to suggest that the longest arrow represents the overall reaction.
Answer:
The overall chemical reaction is exothermic.
