what was the answer of the cracking one? in which a product had 0.5 mole fraction?


i chose the one with C18 ..i think that was choice b. what did u put? :)
u also chose a random one? or u calculated it?


i actually calculated it..and it turns out to be B. my friends too got the same ans.. but of course we still cant say its 100% correct.

lower higher lower

Paper was Tricky actually , really made you think and check your Concepts . I being an A2 student got pissed as already having done p4,p5 i wasn't ready to think "once again" did all of it . However guessed randomly on about 5-6 question which were making me think! p.s What was the enthalpy change +720 no ?

What were the options in the cracking of hydrocarbons question? What were options C and D, to the very least?
