Given that

298K298K

−382.64kJmol−1- 382.64kJmol^{- 1}

−145.6JK−1mol−1- 145.6JK^{- 1}mol^{- 1}

Heat of formation of acetylene is.

A

298K298K

B

mol−1mol^{- 1}

C

kJmol−1kJmol^{- 1}

D

kJmol−1kJmol^{- 1}

Answer

kJmol−1kJmol^{- 1}

Explanation

Solution

Aim: 1000oC1000^{o}C.

eq. (ii) + eq. (iii) → eq. (iv) – eq. (i)

find the required result.
