Over the past few weeks, we learned about chapter 9. This chapter contains few things that we had encountered during our foundation and previous chapter of PCP which is Hess Law and enthalpy tables. Although we have studied Hess Law before, but this chapter is more deep and a bit different compare to Hess Law we learned before. Other than that, this chapter also include energy balance on reactive process. In this subchapter, we have to master two different type of method in solving energy balance. The method is heat of formation and heat of reaction method. The reason we have to completely understand both methods are because some question or problem have limited information, thus just by knowing one method is not enough and the problem might not be solved. Few weeks after study regarding chapter 9, and two days before mid-sem break, we had a test 2 which consist of 4 question. Two questions are from Hess Law, and the other 2 are energy balance.
