1.	723 KJ mol""^(-1) heat is released when 1 molemethanol combustions in present of O_(2). What amount of heat is enlisted of one mole of O_(2) is used?
Answer» <html><body><p>241 kJ<br/>723 kJ<br/>482 kJ<br/>924 KJ</p>Solution :Combusion reaction of methanol, <br/> `CH_(3) OH_((l)) + (3)/(2) O_(2(g)) = CO_(2(g)) + 2H_(2) O_((l)) , <a href="https://interviewquestions.tuteehub.com/tag/delta-947703" style="font-weight:bold;" target="_blank" title="Click to know more about DELTA">DELTA</a> <a href="https://interviewquestions.tuteehub.com/tag/h-1014193" style="font-weight:bold;" target="_blank" title="Click to know more about H">H</a>= -723` kJ <br/> 1 mole `(3)/(2)` mole <br/> therefore `(3)/(2)` moles `O_2` is used in this reaction. <br/> If 1 mole `O_2` is used. <br/> then free <a href="https://interviewquestions.tuteehub.com/tag/energy-15288" style="font-weight:bold;" target="_blank" title="Click to know more about ENERGY">ENERGY</a> `= (2)/(3) xx` combustion energy 723 <br/> `= 482` kJ</body></html>
