Principle Chemical Process 2 Part II | wanah :)'s Profile

After done test 1, we continue for second chapter which is about energy balance for reactive process. In this chapter, I have learnt about heat of reaction, how and when to use it and also about Hess’s Law. Besides that, I also learnt about heat of formation and heat of combustion as well as how to calculate it. We also had learnt about energy balance techniques for reactive process and a few tips that we need to be consider.

For the test 2, it is all about what we learnt in chapter 2 and I think this time I did well even I still did a few mistakes during the test. However, I’ve got better result than test 1 and Alhamdulillah it is from my own efforts. By the way, thanks also to my lecturer because always teach me and urge me to study hard for the test and final. 

Then, we learnt chapter 3 which is about second law of thermodynamics which is covered about the statement of the law of thermodynamics, heat engine, heat pump, refrigerator, carnot cycle, what is entropy, entropy generation and as well as efficiency. For the information, Carnot cycle is the best process rather than irreversible process.

After done with that chapter, we move on to chapter 4 which is about power and refrigeration systems which is also related to carnot cycle. This topic includes power systems, the Rankine cycle, effect of pressure and temperature on the Rankine cycle, Refrigeration cycles. However, our test 3 just covered about what we had learnt in chapter 3 but it still a lot of thing we need to know.

On 18 December 2012, before test I think I can do it because I’m understand I guess but during the test I kept asking myself “What is this??Am I able to answer this?”. However I’m still answer it but I’m not too sure either my answers are correct or not. After the test, one of my friends said, “It’s easy for you right?I can see your paper full of answers”. But what I can said,”Your eyes must be mistaken. It’s also hard for me okay. Don’t judge me from what you see”. Then what I can be said is this test is hard for me and my friends. What I can do is just waiting for the result.
