[sakshi.dhiman@rocketmail.com]

But 1 numerical was out of syllabus

[rbharti222@yahoo.co.in]

Which question...can u post that question????

[rbharti222@yahoo.co.in]

If u r asking abt equilibrium question...!!! Substitute the values of the conc. of products and reactants in the eq. for equ. constant at 1500 K{CONC OF [N2]=.80-X..[O2]=.20-X…[NO]=2X}. And then u wud get a quadratic eq. But solving the quadratic eq. is tough..conc of No2 was 12.6×10^-4..!!! It was out of syllabus!! so there will be grace marks for sure!!

Yeah it was easy for all including me,,but i got to tell every ‘ THE HINDU ‘ newspaper reader who studied according to the responses about the syllabus for CBSE 2012 Board exam given by the CBSE authorities on request in ” ASK CBSE ” section of ‘Education PLus’, a supplement of THE Hindu, even though they had clearly said that Catalysis,Ideal Solutions and some other,topics are not included. But For the board exam,questions came from these excluded topics. So i request this website administrators to request CBSE to give the marks to all for all the questions out of syllabus,,as students through The Hindu had contacted Cbse authorities and clarified again and again that those topics are not really there.If they are not ready to give the mark,i think we should sue Hindu newspaper. Here a Few good students are actually getting punished for reading newspapers.
