1.	on the basis of thermochemical equation a,b and c, find out which of the algebraic relationships given in option a , to d . Is correct ? a. C(graphite)+ O_(2)(g) to CO_(2)(g), Delta_(c)H = x kJ mol^(-1) b. C(graphite)+ 1/2O_(2)(g) to CO_(2)(g), Delta_(c)H = y kJ mol^(-1) Co(g) + 1//2 O_(2)(g) to CO_(2)(g), Delta_(c)H = zkJ mol^(-1)
Answer» z=x+y x= y-z x = y +z y=2z-x Solution :`C+O_(2)toCO_(2)(g),Delta_(r)H= XKJ mol^(-1) ......(i)` C (graphite) `+1/2O_(2)(g)to CO(g),Delta_(r)H= y KJ mol^(-1).....(ii)` `CO(g)+1/2O_(2)(g)toCO_(2)(g),Delta_(r)H=zkJ mol^(-1) ...... (iii)` ltbr gt `(i)=(ii)+(iii)` x=y+z
