The heat change during the reaction 24g C and 128g S following he change `C+S_(2)rarr CS_(2) , Delta H=22K` cal

Options

A. 22 K cal
B. 11 K cal
C. 44 K cal
D. 32 K cal

Answer

C

Explanation

`{:(,C,+,S_(2)rarr,CS_(2),Delta H=22 KCal),("initially :",(24)/(12),,(120)/(64),0),(,=2mol,,=2mol,),("after "Rx^(n),0,,0,2mol):}`
According to equation for the formation of 1 mole `CS_(2)`
`Delta H=22 kCal` so for 2 mol `CS_(2)` formation `Delta H=2xx22=44 kCal`
