Column I Column II

A $E_{a} (f)$ p $- 10 k J m o l^{- 1}$

B $E_{a} (b)$ q $40 k J m o l^{- 1}$

C $Δ_{r} H$ r $30 k J m o l^{- 1}$

D $E_{Threshold}$ s $50 k J m o l^{- 1}$

A - (b), B - (a), C - (d), D - (c)

A - (c), B - (b), C - (a), D - (d)

A - (a), B - (d), C - (c), D - (b)

A - (d), B - (c), C - (b), D - (a)

$(a \to c)$ Activation energy for forward reaction $= 50 - 20 = 30 k J m o l^{- 1}$
$(b \to b)$ Activation energy for backward reaction $= 50 - 10 = 40 k J m o l^{- 1}$
$(c \to a) Δ_{t} H = Δ_{p} H - Δ_{R} H = 10 - 20 =$
$- 10 k J m o l^{- 1}$
$(d \to d) E_{threshold} = 50 k J m o l^{- 1}$
