For reaction
`2A(g)+3B(g)to4C(g)+D(s)` Calulate work involved during system reaction if reaction occurs at constant pressure and 300K:

Heat of reaction A(s) + B(g) rarr 2C(g) is 40 kJ at 300 K and constant volume. Hence, heat of reaction at constant pressure and at 300 K is,

Heat of reaction A(s) + B(g) rarr 2C(g) is 40 kJ at 300 K and constant volume. Hence, heat of reaction at constant pressure and at 300 K is,

For the reaction, A(s)+3B(s)to4C(s)+D(l) DeltaH and DeltaU are related as-

For a reaction 2A(g)+2B(g) rarr 2C(g)+D(g) . If heat of reaction at constant pressure is -28 K.cal. The heat of reaction at constant volume at 27^(@)C is

Statement-1 : For reaction 2A(g)+3B(g)to4C(g)+D(g) vapour density remains constant throughout the course of reaction. Statement-2 : In all gaseous chemical reactions vapour density reamain constant.

For the reaction, A(s) + 3B(g) rarr 4C(g) + d(l) Delta H and Delta U are related as :
