A student forgot to add the reaction mixture to the round bottomed flask at 27°C, but he/she placed the flask on the flame. After a lapse of time, he realised his mistake. Using a pyrometer, he found that the temperature of the flask was 477°C. What fraction of the air would have been expelled out ?
