Using standard heat of formation we can calculate the standard enthalpy Change for this reaction.
What is reaction.
reaction is a process that's leads to the chemical transformation of one set of chemical substances to another.
Sol-In this question they have us that using standard heat of formation, so here we have to use standard heats of formation, so by using standard heats of formation, we have to calculate standard enthalpy change. So here we have to calculate standard enthalpy change for the particular reaction. So what is the given reaction for that? We have to find out standard, enthalpy change, so the reaction here. It is c that is the solid graphite plus oxygen gas. It gives rise to c to gas. This is the reaction for this reaction. We have to find out standard heat of formation. That is so here we have to. By using standard heat of formation, we have to calculate standard enthalpy change. That is the question, so we know that standard heat of formation of graphite- that is the graphite graphite. That is equal to 0 kilo, joules per mole, so here there's a hitch of formation of oxygen gas, oxygen gas that is equal to 0. So this is the 0 kilo joules per mole and here also delta hedge of formation of oxygen. Gas is equal to 0 kilo, joulesper mole, so delta h of the formation of carbon dioxide gas. So it will be, it is so what it be. It will be. The minus 393.5 kilo joules per mole, so delta h of formation of carbon dioxide gas, is equal to minus 393.5 kilo joules per mole. This is the ans.
