(P) $Cis-2-butene⟶trans-2-butene,\Delta H_1$

(Q) $Cis-2-butene⟶1-butene,\Delta H_2$

(R) $\mathrm{Trans}-2-\mathrm{butene}$is more stable than $\mathrm{cis}-2-\mathrm{butene}$

(S)  Enthalpy of combustion of  $1 -butene,$

$\Delta H=-649.8 kcal/mol$

(T) $9\Delta H_1+5\Delta H_2=0$

(U) Enthalpy of combustion of trans$-2-butene, \Delta H=-647.0 kcal/mol$

The value of  $\Delta H_1\mathit{ }and\mathit{ }\Delta H_2$ in $kcal/$ mole are :
