Consider the following nine phase transformations.
`H_(2)O(s,1atm,273 K)rarr H_(2)O(l,1 atm, 3273 K)`
`H_(2)O(s,1atm,300K)rarr H_(2)O(l,1 atm, 300 K`)
`H_(2)O(s,1 atm,200 K)rarrH_(2)O(l,1 atm, 200 K`)
`H_(2)O (s,0.5 atm, 273 K)rarrH_(2)O`(l,0.5 atm 273 K)
`H_(2)O(s,2 atm, 273 K)rarrH_(2)O (l,2 atm,273 K)`
`H_(2)O(l, 1 atm, 400 K)rarrC_(6)H_(6)`(g),1atm, 353K)
`C_(6)H_(6)(l,1 atm, 400 K)rarrC_(6)H_(6)(g,1atm,400 K`)
`C_(6)H_(6)(l,1atm,300 K)rarrC_(6)H_(6)`(g,1atm,300K)
`C_(6)H_(6)(l,2atm,327 K)rarrC_(6)H_(6)`(g,2atm,323 K)
Given : `T_(nbp)`of `C_(6)H_(6)(l)=353 K`
Now a four digit number abcd is fined as follows: Digit a It is number of phase transformations for which `DeltaS_(total)=0`
Digit b It is number of phase transformations for which `DeltaS_(total)lt0`
Digit c It is number of phase transfprmation for which `DeltaS_(total)gt0` Digit d It is number of phase transformation for which `DeltaHgt0`
Determine the number abcd
[Note:If a =1, b=2,c=3 and d=4, then answeris 1234]
