1q.10. ) y not a and c both .. becoz circle is also one form of ellipse ..
also i got a negative marking in it but this was a multiple choice so y negative... ?
q.50) y not catalyst? (does cat helps reaching eqm faster or also increase the amount of product in equibm.?? ... jus a bit confused...)
q.52 ) i couldn understand.. PLEEEEEASE EXPLAIN !
Q.55)its multiple choice but i got -ve marks :(
1huh!i thot my marks wud increase!
but it has decreased!
and most surprisingly.... there has been no extra wrong or no extra right!
very very very very confused! [7]
1IN Q47 we are asked about freezing point of solution but the ans given is depression in freezing pt.
3sir for the 26 th question the force depends on the area of cross section. dF = Ïgw ydy / sinα
therefore the force decreases on increasing the angle of the inclination.
1357Q50 catalyst fastens both the forward and backward reaction, but doesn't change the amount in equilibrium
Q55 will be corrected
52 think in this way
ΔG3=ΔG1+ΔG2
nFE3=nFE1+nFE2
1hii sir and happy new year.....
i didn't gave the test but i download the test yesterday......
but i wanted to get answers of the test, so can i get it.....
1sir in q7 we are given the cond x>2y

so for x=2 & y=1 we are gettin d ....
plz help
1in ques 34 if we place d two arcs independently then they shud have equal and opp G field as together they have zero hence a (by superposition)
1357In Q72 explanation given is not clear
it should be as work done in process BC - work done in process DA
As the work done in process BC is negative and greater than DA, total work that comes out is negative
Work done is -TΔS
1Q72 Total work done in the process
Your Answer: 576 J
Correct Answer: -576 J
Score: -1
Explaination :
Area of the curve=-576 J
But the area under curve = (Sd-Sa)*400 + (Sa-Sd)*300 = 576
1sir....
wht's wrong in my 10th ques? i'm not able to get d expln....
