The graph relates in K_(eq) Vs 1/T for a reaction. The reaction must be :

Answer»

exothermic
endothermic
`DeltaH` is NEGLIGIBLE
spontaneous

Solution :`Delta G^(@)=RT -RTl nk, l nk =(-DeltaH^(@))/(RT)+(deltaS^(@))/(R)`
`:.` slope= `(-DeltaH^(@))/(R)` = .+. Ve `IMPLIES DeltaH^(@) LT 0`
`:.` exothermic
