Derive a model for an ideal isothermal plug flow reactor (pfr) in which the reaction 2a + b takes place. let the forward rate constant be k, and the reverse rate constant k2 (both based on a), the reactor cross sectional area be ac, the velocity v ef/a), and the feed concentration caf. initially the rector contains no a. make sure that your model is complete, i. e. it provides all information needed to solve it. classify your model (e. g., linear ordinary differential equations). how do your model equations change if you also assume steady state?

According to periodic trend, which of the following most likely has the highest ionization energy? kr be ni sc

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion. what is the frequency f of oscillation?
