MCQ (Single Correct Answer)

-1

Hydrolysis of sucrose is given by the following reaction.
Sucrose + H₂O ⇌ Glucose + Fructose
If the equilibrium constant (K_c) is 2 $$ \times $$ 10¹³ at 800 K, the value of $$\Delta r{G^\Theta }$$ at the same temperature will be :

8.314 J $$mo{l^{ - 1}}{K^{ - 1}} \times 300K \times In(2 \times {10^{13}})$$

8.314 J $$mo{l^{ - 1}}{K^{ - 1}} \times 300K \times In(3 \times {10^{13}})$$

$$ - $$ 8.314 J $$mo{l^{ - 1}}{K^{ - 1}} \times 300K \times In(4 \times {10^{13}})$$

-8.314 J $$mo{l^{ - 1}}{K^{ - 1}} \times 300K \times In(2 \times {10^{13}})$$
