Given that 2C(s)+2O_(2)(g)rarr2CO_(2)(g), DeltaH=-787 kJ H_(2)(g)+(1)/(2)O_(2)(g)rarrH_(2)O(l), DeltaH=-286 kJC_(2)H_(2)(g)+2(1)/(2)O_(2)(g)rarr2CO_(2)(g)+H_(2)O(l), DeltaH=-1301 kJHeat of formation of acetylene is

Answer»

`-1802` kJ
`+1802` kJ
`-800` kJ
`+228` kJ

Solution :Aim:`2C+H_(2(g))rarrC_(2)H_(2(g))`.
eq. (II) + eq. (iii) `rarr`eq. (iv) - eq. (i)
find the required RESULT.
