Which of the following graph represents exothermic reaction ?

Options

A.
B.
C.
D.

Answer

D

Explanation

In `K_(p)= "In" (A_(f)/A_(f))=((E_(af)-E_(af)))/(RT)= "In" (A_(f)/A_(f))=(DeltaH)/(RT)`
For exothermic, `DeltaH=-ve, (as E_(af) gt E_(af))`
`:' In K_(p)= In (A_(f)/A_(f))+(DeltaH)/(RT)`
`Y=c+mx`
Since the slope is positive, hence the correct option is (d).
