i have a chemistry lecturer called wang dong an. a.k.a D.A Wang. he is a really interesting person. he always walks into the lt frowning. And throughout the whole lecture, he uses 100% of his energy, talking very passionately about chemistry with all his gestures. at the end of the lecture, he will perspire profusely and say "why isnt the air con switched on? "when all the students are freezing..
yesterday, he went through one of the tutorial with us.. there was one qn i that i couldnt solve when i was attempting it. and to my bewilderment.. he actually said something really unbelievable. ok if you are free try doing this qn..
4) Chlorine gas is produced at very high temperature by a reaction known as Deacon's process. 4HCl(g) + O2(g) 2H2O(g) + 2Cl2 (g). The equilibrium mixture in a 50-litre vessel contained the following: 37.5 mol of HCl, 1 mol of O2, 40 mol of H2O and 40 mol of Cl2.
(a) Calculate the equilibrium constant Kc.
(b) How many moles of O2 must be added to increase the concentration of Cl2 to 0.9 mol L-1?
(c) How many moles of water must be removed in (a) to increase the concentration of Cl2 to
1.0 mol L-1?
for qn c, he said the answer was that it was impossible to solve. maybe it was possible to find an answer in a parallel dimension somewhere but we dont know. So we cannot say that the question is wrong. nope. standard answer shld be that you state that it cannot be solved and explain why.. oh yea. so now i get to doubt the question? thanks man.. lol
was supposed to post this a few days ago but i didnt get to finish typing.. anyway i had a great weekend... AND recess week is coming soon. yea!
