Enthapy of combustion `(Delta_(C ) H)` depens on
(i) whether combustion is carried out in constant volume calorimeter of constant pressure calorimeter
(ii) the physical state of the substances
(iii) the temperature at which combustion is carried out
(iv) the amount of xygen present

A

(i),(ii),(iii)

B

(i),(ii),(iii),(iv)

C

(iii),(iv)

D

(i),(ii)

Text Solution

Verified by Experts

The correct Answer is:
A
Enthalpy of combustion is independent of the amount of oxygen used because combustion, by definition, is always carried out in excess of oxygen.
