I need help on question 6? 5) Think about your temperature measurements. In the end, you will need to use AT todescribe the heat for the reaction (as you did in CHEM& 161). For each part of theexperiment, state how the values for the initial and final temperatures are obtained. Drawa graph, if needed. Be as explicit as you can to demonstrate you know how to get thevalues you will need to do your postlab.a) Part Ai. T.?ii. T₁?b) Part Bi. T₁?ii.
