Answer» <html><body><p></p>Solution :This <a href="https://interviewquestions.tuteehub.com/tag/reaction-22747" style="font-weight:bold;" target="_blank" title="Click to know more about REACTION">REACTION</a> is exothermic. So at lower temperature the forward reaction <a href="https://interviewquestions.tuteehub.com/tag/take-662846" style="font-weight:bold;" target="_blank" title="Click to know more about TAKE">TAKE</a> <a href="https://interviewquestions.tuteehub.com/tag/place-1155224" style="font-weight:bold;" target="_blank" title="Click to know more about PLACE">PLACE</a>. So in mixture `NO_2` decreases so brown colour. decreases. If the vessel kept in hot water then the reaction take place in <a href="https://interviewquestions.tuteehub.com/tag/reverse-1188140" style="font-weight:bold;" target="_blank" title="Click to know more about REVERSE">REVERSE</a> <a href="https://interviewquestions.tuteehub.com/tag/direction-1696" style="font-weight:bold;" target="_blank" title="Click to know more about DIRECTION">DIRECTION</a> and concentration of `NO_2` increases so brown colour increases.</body></html>
