Q.2 (b)(iii) please explain this question
As it is exothermic reaction sign will be -ve.http://pastpapers.papacambridge.com/Cambridge International Examinations (CIE)/AS and A Level/Chemistry (9701)/2015 Nov/9701_w15_qp_22.pdf
Q.2 (b)(iii) please explain this question
elmansy kp= partial pressure of products^n / partial pressure of reactants^m
partial pressure = total pressure X no.moles of / total number of moles.
pressure = 2atm
partail pressure of N2O4 = 2 X (40/100) = 0.8
partail pressure of NO2 = 2 X (60/100) = 1.2
Kp = 0.8 / (1.2)^2 = 0.56 .
read the book this was a simple question
A is potasssiumElement X forms X- ions that can be oxidised to element X by acidified potassium maganate (VII). Ehat could be the values of the first four ionisation energies of X?
A) 418 3070 4600 5860
B) 577 1820 2740 11600
C) 590 1150 4940 6480
D) 1010 1840 2040 4030
Ans is D. Can someone pls explain?
