Using an enthalpy cycle, estimate rH for the decomposition of K2O2 to K2O. The size of the ions are as follows, O is 140pm,K is 138pm, and O22 is 167pm.xH=845kJmol1 Ulatt=r++rkvz+z For the Kapustinskii equation for K2O2 k= v= z= pmkJmol1 latl(K2O)= IOK2O2)= The enthalpy of decomposition, rH, for the decomposition of K2O2 to K2O= KJmol1 Using an enthalpy cycle, estimate rH for the decomposition of K2O2 to K2O.
