Is a packed bed reactor and a fixed bed reactor the same thing? What's the difference?
What is the difference between mass specific heats and molar specific heats. For metals, are they different or approximately the same? Why? Explain
5. Specific Surface Area: Determine the specific surface area of the following objects: a. A Montmorillonite clay particle: 100nm in diameter, 1nm thick b. A 1" Steel Rod, 6 inches long c. A 5" diameter orange cut into 4 slices
A catalytic reaction is being carried out in a packed bed in the annular space between two concentric cylinders with inner radius Ri = 1.5 cm and outer radius R2 = 1.8 cm. The entire surface of the inner cylinder is insulated, and it has a uniform outer temperature of T2. The rate of generation of energy per unit volume as a result of a chemical reaction is 5x100 W/m and it is uniform throughout the annular reactor. The effective...

what is the difference between routine oxygen consumption and mass specific oxygen consumption?
An asteroid has a surface area of 5 m2. What would its surface area be if its linear dimension is doubled? Please, explain to me how should I approach this problem because I really don't get it :-(
Consider a nanotube made of carbon atoms. What value do the inner and outer radius have if : - The specific surface area is 230 m²/g. - The outer radius is twice the inner radius. - The tubes are open so that the area is the sum of the inner and outer surfaces.
