Answer to Question #164575 in Atomic and Nuclear Physics for Sadi

Question

In the synthesis of Mo nitrides, there were three synthesis variables: b₁ (the heating rate from 350-450^oC, b₂ (the heating rate from 450-700^oC), and space velocity, SV (in moles/hr of total gas flowrate divided by moles of Mo metal in the prepared catalyst).

A) (1 pt.) Which variable correlated with increasing surface area?

B) (1 pt.) Why does the answer to A make sense?

C) (4 pts.) If the bubbling gas in a porous gel collapse, then the material is called a ___________; if the pores remain, then it is called an _____________. The gas "solvent" commonly used to extract template molecules is ______________________ if it is above its ___________________.

D) (2 pts.) What did catalytic activity for pyridine hydrodenitrogenation (HDN) correlate with?
