This section focuses on calculating equilibrium moles from initial amounts and changes in moles (using "ICE" tables). For example, in the reaction

CH4(g)+H2O(g)⇌CO(g)+3H2(g)CH sub 4 open paren g close paren plus H sub 2 O open paren g close paren is in equilibrium with CO open paren g close paren plus 3 H sub 2 open paren g close paren

Partial Pressure=Mole Fraction×Total PressurePartial Pressure equals Mole Fraction cross Total Pressure This final part involves writing the Kpcap K sub p expression for specific reactions. Unlike Kccap K sub c , which uses concentrations, Kpcap K sub p
