Tardigrade Admin · Accepted Answer

Activation energy of forward reaction = a Threshold energy =b ∴ Heat of reaction, Δ H r = c ∴ Reaction is exothermic

Q. The potential energy diagram for a reaction $R \to P$ is given below.

$Δ H^{\circ}$ of the reaction corresponding to the energy:

$a$

$b$

$c$

$a + b$

Activation energy of forward reaction $=$ a

Threshold energy $= b$

$∴$ Heat of reaction, $Δ H_{r} = c$

$∴$ Reaction is exothermic

Q. The potential energy diagram for a reaction R→P is given below. ΔH∘ of the reaction corresponding to the energy:

a

b

c

a+b

Activation energy of forward reaction = a Threshold energy =b ∴ Heat of reaction, ΔHr​=c ∴ Reaction is exothermic
