The elementary irreversible organic liquid-phase reaction A+B → C

is carried out adiabatically in a flow reactor. An equal molar feed in A and B enters at 27C, and the volumetric flow rate is 2 dm^3/s and CAO 0.1 kmol/m^3.

a. Plot and then analyze the conversion and temperature as a function of PFR volume up to where X = 0.85. Describe the trends.

b. What is the maximum inlet temperature one could have so that the boiling point of the liquid (550 K) would not be exceeded even for complete conversion?

c. Plot the heat that must be removed along the reactor [Q vs V] to maintain isothermal operation.

d. Plot and then analyze the conversion and temperature profiles up to a PFR reactor volume of 10 dm^3 for the case when the reaction is reversible with KC 10 m^3/kmol at 450 K. Plot the equilibrium conversion profile. How are the trends different than part (a)?

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
