acetaldehyde (CH3CHU) in aqueous For the reaction between hydrocyanic acid (HCN) and solution, HCN(A) + CH3CHO(B) - CH2CH(OH)CN the rate law at 25°C and a certain pH is(-ra)=KACACB, where ka=0.210 L mol"min" (see problem 4-6). If the reaction is carried out at steady-state at 25°C in a CSTR, how large a reactor (V/L) is required for 75% conversion of HCN, if the feed concentration is 0.04 mol L-l for each reactant, and the feed rate is 2 L min!?

When we discussed hybrid orbitals, we also learned two types of bonds, sigma and pi bonds. a. Considering our orbital overlap model of covalent bonding, what is the main difference between sigma and pi bonds? b. Which bonds are stronger, sigma bonds or pi bonds? c. The chemical structure for formaldehyde is given below. Tell the hybridization of the C atom, and identify the sigma and pi bonds.
[References) EXERCISE Sigma Bonding Sigma bonds can form between different types of orbitals. The main criterion for sigma bond formation is that the two bonded atoms have valence orbitals with lobes that point directly at each other along the line between the two nuclei. The images below show the shapes of two orbitals on adjacent atoms. Choose all of the combinations that will lead to formation of a sigma bond. (Select all that apply.) [References) None of these Check Next...
