   Pressure can be thought of as the concentration of a force on an area and can be calculated using the equation: Pressure = force ÷ area Force is measured in Newtons (N). Area can be cm² or m² and so pressure is measured in N/cm² or N/m². For example a person might weigh 400 N and stand on one foot which has an area of 80 cm² so the

   May 1, 2016 · Example : A mixture contains 0.2 moles N2, 0.5 moles O2 and 1.2 moles of CO2.If the total pressure is 3kPa. What are the partial pressures of the 3 gases? Total moles of gas = 0.5 + 1.2+ 0.2 = 1.9. mole fraction = 0.2/1.9 mole fraction = 0.5/1.9 of N2 =0.105 of O2 =0.263. Partial pressure =0.105x 3 Partial pressure.

   What is the partial pressure of a gas in a mixture?

   • The partial pressure of a gas in a mixture is the pressure that the gas would have if it alone occupied the volume occupied by the whole mixture. A mixture contains 0.2 moles N2, 0.5 moles O2 and 1.2 moles of CO2.If the total pressure is 3kPa. What are the partial pressures of the 3 gases? Only include gases in the Kp expression.

   What is a gas pressure?

   • Pressure is defined as the force applied divided by the area over which it is applied. A gas pressure results from the many collisions between gas particles and a surface. The SI unit of pressure is the newton per square meter (N/m2) called the pascal (Pa). A pascal is very small so it is often reported in thousands of pascals or kilopascals (kPa).

   Does the pressure change when a gas is compressed?

   • When the pressure is constant, it does not change. This is because the total number of moles of gas remains the same. Compressing the gas into a smaller volume does not alter the total number of gas molecules, so the total number of moles remains constant.

   What happens if gas is heated at constant pressure?

   • When a gas is heated at constant pressure, the piston moves and the volume increases (Charles’s law), resulting in an increase in the distance between molecules. However, since the pressure remains constant, the pressure itself does not change. The total number of moles of gas remains the same.
