A plot of In K against 1/T (abscissa) is expected to be a straight line with intercept on ordinate axis equal to

Answer»

`(Delta S^@)/(2.303 R)`
`(Delta S^@)/(R )`
`-(Delta S^@)/(R )`
`R xx Delta S^@`

SOLUTION :
`Delta G^@ = -RT lnK`
`Delta H^@ - T Delta S^@= -RT ln K`
`ln K = (-Delta H)/(RT) + (Delta S^@)/(R )`
comparing with
`y = mx+ c `
` THEREFORE ` y INTERCEPT is `(Delta S^@)/(R )`
