A) \[10\,\text{at}{{\text{m}}^{-1}}\]
B) \[10\,\text{atm}\]
C) 10
D) 1
Correct Answer: A
Solution :
For the reaction, \[2S{{O}_{2}}(g)+{{O}_{2}}(g)2S{{O}_{3}}(g)\] Given that, \[\Delta {{G}^{o}}=-690.9R,T=300\,K\] From the formula, \[\Delta {{G}^{o}}=-RT\,\ln \,K\] \[-690.9\,R=-R\times 300\times \ln \,K\] or \[\ln \,k=\frac{690.9}{300}=2.303\] or \[=2.303\,\log \,K=2.303\] or \[K={{10}^{1}}=10\] unit of \[K=(atm){{\Delta }^{n}}={{(atm)}^{2-3}}={{(atm)}^{-1}}\] \[\therefore \] \[K=10\,at{{m}^{-1}}\]You need to login to perform this action.
