In an industrial process, carbon dioxide (CO2) at 500 K, 1 bar enters a heated mixing chamber at steady state, where it mixes with nitrogen (N2) entering as a separate stream at 300 K, 1 bar. The mass flow rate of CO2 is 0.1 kg/sec. The mixture exits at 1 bar with a molar analysis of 47.5% CO2, 52.5% N2. The heat transfer to the mixing chamber is 100 kW. Kinetic and potential energy effects can be ignored and the gases behave as ideal gases. Determine: (a) the mass flow rate of exiting mixture, in kg/sec. (b) the temperature of the exiting mixture, in K. (c) the rate at which entropy is produced, in kW/K , if the boundary temperature at which the heat transfer occurs is 1500 K. (d) if the mixing chamber is not heated, will there be any entropy production

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

the atomic number of carbon is six, which means that a carbon atom has six protons. carbon has three naturally occurring isotopes: carbon-12, carbon-13, and carbon-14. which of these statements are true about carbon and its isotopes? select all that appl
