qtn 5b(ii) can anyone explain me this in detail?
can u plzz explain the (iii) as wellGibbs free energy = H - TS
S = (H-G)/T *1000
You multiply by 1000 because the unit for S is J/Kmol, while the units for H and G are kJ.
Hence, the answer is 14.1.
can u plzz explain the (iii) as well
5 a (ii) ??? should i solve or u had doubt in 5 b (ii)View attachment 61578

This is the AS/A level thread but anyway,View attachment 61644View attachment 61645View attachment 61644 View attachment 61645 Can someone explain for question d ??
Yes it can have. Strong electronegative element N is present in other propanamine that can form H bonds with hydrogen present in the other propanamine.Cn dere b H- bonds b/w Ch3CH2CH2NH2 molecules? Lyk the +ve H of 1 molecue to a -ve N of a diff molecule?
