Chemical Engineering :: Stoichiometry
- The net heat evolved or absorbed in a chemical process, i.e. total change in the enthalpy of the system is independent of the
- Pick out the wrong statement.
- A gas mixture contains 6 moles of H₂ and 2 moles of N₂. If the total pressure of the gaseous mixture is 4 kgf/cm² ; then the partial pressure of N₂ in the mixture will be __________ kgf/cm² .
- The heat capacity of a substance is
- A rigid vessel containing three moles of nitrogen gas at 30°C is heated to 250°C. Assume the average capacities of nitrogen to be Cp = 29.1 J/mole.°C and, Cv = 20.8 J/mole.°C. The heat required, neglecting the heat capacity of the vessel, is
- The temperature at which real gases obey the ideal gas law over a wide range of pressure is called the __________ temperature.
- The pH value of a solution is 5.9. If the hydrogen ion concentration is decreased hundred times, the solution will be
