$2.$ You want to know the standard heat of reaction for the following reaction:C$2$H$4($g$)+2$Cl$2($g$)$ C$2$HCl$3($l$)+$ H$2($g$)+$ HCl $($g$)$a$)$ Calculate the standard heat of reaction using the following reactions:C$2$H$4($g$)+2$Cl$2($g$)$ C$2$H$2$Cl$4($l$)+$ H$2($g$)$ where $$Hr $=-385\mathrm{.}76$ kJ$/$molC$2$H$2$Cl$4($l$)$ C$2$HCl$3($l$)+$ HCl $($g$)$ where $$Hr $=-35$ kJ$/$molb$)$ Calculate the standard heat of reaction using the heats of formation from Table B$\mathrm{.}1,$ giventhat the standard heat of formation for trichloroethylene is $-276\mathrm{.}2$ kJ$/$mol$.$c$)$ Calculate the standard heat of reaction using the heats of combustion from Table B$\mathrm{.}1,$given that the standard heat of combustion for trichloroethylene is $-947\mathrm{.}7$ kJ$/$mol$,$ forhydrogen chloride is $-95\mathrm{.}31$ kJ$/$mol$,$ and for chlorine gas is $-169\mathrm{.}23$ kJ$/$mol$.$d$)$ Are the three standard heats of reaction the same? If not, how much do they differ?e$)$ If $300$ mol$/$h of C$2$HCl$3($l$)$ is produced, how much heat is transferred in the process?f$)$ If the molar flow rate triples and the first reaction is doubled, how much heat is transferredin the process?
