Which of the following is correct for the change shown below ?
`underset(298K)(aA+bB) overset(Delta_(r)S_(1)^(@))rarrcunderset(298)(C+dD)`
`Delta_(r)S_(1)^(@)darr " " uarr Delta_(r)S_(4)^(@)`
`underset(0K)(aA+bB) overset(Delta S_(3)^(@))rarr cunderset(0K)(C+dD)`

A

`Delta_(r)S_(1)^(@) = cS_(C)^(@) + dS_(D)^(@) - (aS_(A)^(@)+bS_(B)^(@))`

B

`Delta_(r)S_(2)^(@) = -[aS_(A)^(@)+bS_(B)^(@)]`

C

`Delta_(r)S_(3)^(@) = 0`

D

`Delta_(r)S_(4)^(@) = -[cS_(C)^(@)+dS_(D)^(@)]`

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`Delta_(r)S_(4)^(@) = sumS_(P) - sum S-(R) = CS_(C)^(@)+dS_(D)^(@) - 0 - 0`
