Question

$3 C_{2} H_{2} (g) ⇌ C_{6} H_{6} (l)$
given that

$G_{m}^{o} (C_{2} H_{2}) = 2.4 \times 10^{5} J$

$G_{m}^{o} (C_{6} H_{6}) = - 1.4 \times 10^{5} J$

Find the value of ${log}_{10} k at 25^{\circ} C$

Open in App

Solution

$Δ G^{o} = {(G_{M}^{o})}_{C_{6} H_{6}} - 3 {(G_{M}^{o})}_{C_{2} H_{2}}$
$= - 1.4 \times 10^{5} - 3 \times 2.4 \times 10^{5}$

$= - 8.6 \times 10^{5} J o u l e$

$- 2.303 R T {log}_{10} k = - 8.6 \times 10^{5}$

$- 2.303 \times 8.314 \times 298 {log}_{10} k = - 8.6 \times 10^{5}$

${log}_{10} k = 150.72$
