A hypothetical reaction, `A rarr 2B`, proceeds via following sequence of steps
`{:(ArarrC,,DeltaH = q_(1),,,),(CrarrD,,DeltaH = q_(2),,,),((1)/(2)D rarrB,,DeltaH = q_(3),,,):}`
The heat of reaction is

A

`q_(1)-q_(2)+2q_(3)`

B

`2q_(1)+q_(2)-2q_(3)`

C

`q_(1)+q_(2)+2q_(3)`

D

`q_(1)+2q_(2)-q_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C

`A rarr C" "Delta H= g_(1)`
`C rarr D" "Delta H =2g_(3)`
`therefore A rarr B" "Delta H=g_(1)+g_(2)+2g_(3)`

An imaginary reaction X rarr Y takes place in three steps X rarr A, DeltaH=-q_(1), " "BrarrA, DeltaH=-q_(2), " "BrarrY, DeltaH=-q_(3) If Hess's law is applicable, then the heat of the reaction (X rarr Y) is :

A certain endothermic reaction: Ararr Product, DeltaH=+ve proceeds in a sequence of three elementary steps with the rate constants K_(1), K_(2) and K_(3) and each one having energy of activation E_(a), E_(2) and E_(3) respectively at 25^(@)C . The observed rate constant for the reaction is equal to K_(3) sqrt(K_(1)/K_(2)). A_(1), A_(2) and A_(3) are Arrhenius parameters respectively. For a reversible reaction, A underset(K_(2))overset(K_(1))(hArr) B, DeltaH=q , if perexponential factors are same. The correct relation is:
