1. The problem statement, all variables and given/known data I am given the following chemical eqn TiCl4(g) + O2 → TiO2 (s) + 2Cl2 I am also given some values on the heat of formation and the entropy of the substances but however only at 300Kelvin and i am given some values and the formula to calculate Cp of the substances The question asks about the heat of reaction when the process is at 1200Kelvin. Im just not too sure how to start. Am i able to just take the heat of formation values at 300K? IF i were to find out the heat of reaction for this process at 300k, is it possible that i integrate the Cp equation with T2 = 1200K and T1=300k?
