Answer: Option A : A △ G ∘ = − 2.303 R T l o g K p = − 2.303 × 8.314 × 298 × l o g ( 2.47 × 10 29 ) j m o l = 163 k j m o l

Calculate △ G∘ for conversion of oxygen to o

Question

Calculate

△ G^{\circ}

for conversion of oxygen to ozone

3 / 2 O_{2} (g) \to O_{3} (g) a t 298 K, i f K_{p}

for this conversion is 2.47

\times

10^{- 29}

(Use log(2.47) = 0.4)

Options:

A . 163 KJ mol−1

B . 2.4 X 102 KJ mol−1

C . 1.63 KJ mol−1

D . 2.38 X 106 KJ mol−1

Answer: Option A
:
A

△ G^{\circ} = - 2.303 R T l o g K_{p} = - 2.303 \times 8.314 \times 298 \times l o g (2.47 \times 10^{29}) \frac{j}{m o l} = 163 \frac{k j}{m o l}
