1. The problem statement, all variables and given/known data If a feed of TiCl4 and O2 at 600 degrees is fed into a reactor and the product is 1500 degrees, how much heat is added or removed? 2. Relevant equations Cp = A + BT + C/T^2 + DT^2 3. The attempt at a solution I managed to find the heat of reaction for the whole process previously as well as the heat of formation for TiCL4 at 1500degrees. Im kind of stuck from here though. Do i integrate the Cp eqn again with T1 as 1500 and T2 as 600?
