Direction (Q. Nos. 57): A given sample of \[{{N}_{2}}{{O}_{4}}\] in a closed shows 20% dissociation in \[N{{O}_{2}}\] at\[{{27}^{o}}C\]and 1 atm. The sample is now heated up to\[{{127}^{o}}C\]and the analysis of the mixture shows 60% dissociation at\[{{127}^{o}}C\]. |
A) 76.66
B) 78.69
C) 66.52
D) 80.24
Correct Answer: A
Solution :
\[0.8a\times 92+0.4a\times 46\] \[=1.2\times a\times M\] at 300 K \[M=76.66\,g\,\,mo{{l}^{-1}}\]You need to login to perform this action.
