Consider the following processes : {:(,DeltaH(kJ //mol) ),(1//2A rarr

1.	Consider the following processes : {:(,DeltaH(kJ //mol) ),(1//2A rarr B ,+ 150 ),(3 B rarr 2C + D,-125),(E+Ararr2D ,+ 350 ):} For B +D rarrE +2C , DeltaHwill be
Answer» `525 kJ //mol` ` -175 kJ //mol` ` -325kJ // mol` ` 325 kJ //mol` Solution :`2 XX `Eqn. (i) `+`Eqn. (ii) -Eqn. (iii) GIVES the REQUIRED EQUATION. `:. DetlaH =2( 150) + ( - 125) -350 =- 175 kJ //` mol.
