18. The heat change during the reaction 24g C and 128g S following the cha
AH = 22K cal
(1) 22 Kcal
(2)11Kcal
(3)44 kcal
(4) 32 kcal​

Answer 1

Answer:

Hi dhavan ..

Having fun in guru's academy?

Answer is 44 Kcal

Explanation:

Answer 2

The heat change during the reaction between 24g C and 128g S is 44 Kcal.

Option (3).

Explanation:

The reaction is given as $C+S_2 \rightarrow CS_2$

Therefore $\frac{24}{12}=2$ mol and  $\frac {128}{64}=2$mol

In the equation, it is given that for the formation of one mole of $CS_2 AH= 22K$ cal (where A is the symbol for delta)

Similarly, for the formation of 2mol of $CS_2$, the AH will be $2\times22$ which is 44K cal.
