Please show me how to work!
Ethane, C2H6(g) can be made by reaction of hydrogen gas with acetylene, C2H2(g). the standard enthalpies of formation of ethane and acetylene are -84.68 and +226.73 kJ mol-1, respectively. what is the reaction enthalpy for the production of one mole of ethane? Write the balanced chemical equation for the reaction first.
C2H2 + 2H2 ==> CH3CH3
dHrxn = (n*dHf products) - (n*dH reactants).
dHrxn = (n*dHf products) - (n*ch reactants)
