The standard Gibbs energies of formation of gaseous cis- and trans-2-butene are 67. 15 kJ mo1-1 and 64. 10 kJ mo1-1, respectively. Calculate the ratio of equilibrium pressures of the gaseous isomers at 298 K.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
