Ethanol to ethylene reaction occurs through ethanol dehydration under the condition of appropriate temperature and the effect of the catalyst. In this case, ethanol is heated with concentration sulphuric acid $($i$.$e$.,$ dehydrating agent$)$ at $1$ atm and $180C$ according to the following reaction:

If $24$ mega$-$joules of heat are added to process $150kg$ of ethanol in a steady flow process, estimate the final temperature of this reaction.
