Correct Answer - B
`2Na_(2)O+2H_(2)to4Na+2H_(2)O`, `DeltaH=+259kJ`
`2[SO_(3)+2NaOHtoNa_(2)SO_(4)+H_(2)O`
`DeltaH=-2xx418=-836 kJ`
`4[Na+H_(2)OtoNaOH+(1)(2)H_(2)`
`DeltaH=-4xx146=-584 kJ`
`2Na_(2)O+2SO_(3)to2Na_(2)SO_(4)`
`DeltaH=-1170`
`:. Na_(2)O+SO_(3)toNa_(2)SO_(4)`,
`DeltaH=(-1161)/(2)=-580.5 kJ`
