By using the information in this problem and data given below, calculate ΔH∘f for 2,3,4-trimethylpentane
Hey there Michelle! Here is the solution to your problem.
Notice that we needed to write a balanced equation for this reaction.
We used ΔH rxn equation, we were given ΔH rxn value, we also had ΔHf of products, we did not have ΔHf O2 simply because it equals to zero, because O2 is in its natural state.
Let us know if you have any questions about this.
