A(s) (d = 1.14 gm/cc)
B(s) (d = 1.5 gm/cc)
A(s)`hArr`B(s) + Heat
If mass of A and B are equal, on increasing the pressure, will for formation of B `uarr` or `darr` ?

Text Solution

Verified by Experts

`A(s)hArrB(s)`
As density of solid B is greater than solid A, `V_(B) lt V_(A)`
`rArrV_(B)-V_(A)=-ve`
since reaction is exothermic, `thereforeDeltaH=-ve`
`rArr(dP)/(dT)=(DeltaH)/(TDeltaV),(dP)/(dT)=+ve`
`rArr` On increasing pressure, the rate of formation of B will be enhanced.
