3 moles of A and 4 moles of Bare mixed together and allowed to come in

1.	3 moles of A and 4 moles of Bare mixed together and allowed to come into equilibrium according to the following reaction A(g) + 4 B(g) hArr 2 C (g) + 3 D (g) When equilirium is reached , there is 1 mole of C. The equilibriumextent of the reaction is
Answer» <html><body><p>`1//4`<br/>`1//3`<br/>`1//2`<br/>1</p>Solution :`{:(,A,+,4 B,hArr,2C,+,3D),("<a href="https://interviewquestions.tuteehub.com/tag/intial-2746226" style="font-weight:bold;" target="_blank" title="Click to know more about INTIAL">INTIAL</a> moles:" ,3,,4,,<a href="https://interviewquestions.tuteehub.com/tag/0-251616" style="font-weight:bold;" target="_blank" title="Click to know more about 0">0</a>,,0):}` <br/> 4 moles of B react with 1 mole of A. Hence , B is the limiting reactant . From 4 moles of B, if reaction were <a href="https://interviewquestions.tuteehub.com/tag/complete-423576" style="font-weight:bold;" target="_blank" title="Click to know more about COMPLETE">COMPLETE</a> , 2 moles of C would be formed . Actual C formed = 1 mole . Hence extent of reaction completed `=1/2` . <a href="https://interviewquestions.tuteehub.com/tag/also-373387" style="font-weight:bold;" target="_blank" title="Click to know more about ALSO">ALSO</a> , when 1 mole of C is formed , out of 4 moles of B taken, 2 moles of B must have reacted . This also shows that the equilibrium extent is 1/2 .</body></html>
