By measuring the equilibrium between liquid and vapor phases of a binary solution at 30°C at 1atm, it was found that xA=0.220 when yA=0.314. Calculate the activities and activity coefficients of both components in the solution. The vapor pressures of the pure components at this temperature are 73kPa and 92.1kPa.

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
