Question

 For complete combustion of ethanol, 

C₂H₅OH(l) +3O₂(g) →2CO₂ (g) + 3H₂O(l)

The amount of heat produced as measured in bomb calorimeter, is 1364.47 kJ mol^-1 at 25°C . Assuming ideality the enthalpy of combustion, ∆_CH, for the reaction will be (R = 8.314 kJ mol^-1)

(A) -1366.93 kJ mol^-1 

(B) -1361.95 kJ mol^-1 

(C) -1460.50 kJ mol^-1 

(D) -1350 kJ mol^-1 

Answer 1

Correct option (A) -1366.93 kJ mol^-1 

Explanation:

Bomb calorimeter gives ∆U of the reaction 

So, as per question
