11. calculate δh for the following diagram. is this considered endothermic or exothermic? 12. label each part of this diagram a -e
Answer
Explanation:
Step1: Calculate $\Delta H$
$\Delta H=H_{products}-H_{reactants}=75 - 25=50$ kJ
Step2: Determine reaction type
Since $\Delta H = 50$ kJ>0, heat is absorbed. So it is endothermic.
Step3: Label diagram in question 12
A: Reactants B: Products C: Activation energy D: Transition - state E: $\Delta H$
Answer:
- $\Delta H = 50$ kJ, endothermic
- A: Reactants; B: Products; C: Activation energy; D: Transition - state; E: $\Delta H$
