A (eth) + B (eth) → P (s) a reaction with side reaction A (eth) + 2B (eth) = Q. P is desired product and Q is not desired.    the reaction is carried out in batch operation mode, explain how shifting to semi batch will reduce amount of Q being produced while maintaing P as it is.  - reaction is zero-order in both components A and B. -low selectivity(0.1%) nP= 60 mol

What is the concentration of A after 20.5 minutes for the reaction A → Products when the initial concentration of A is 0.800 M? (k = 0.00651 M/min)

Q2- The synthesis of ammonia proceeds according to the following reaction N₂ + 3 H₂ -----> 2 NH3 In a given plant, 4202 lb of nitrogen and 1046 lb of hydrogen are fed to the synthesis reactor per hour. Production of pure ammonia from this reactor is 3060 lb per hour. a. What is the limiting reactant. b. What is the percent excess reactant. c. What is the percent conversion obtained (based on the limiting reactant).

Reactant A decomposes as follows: A Rdesired S T U where n, are reaction orders. Qualitatively find what flow (plug, mixed, or inter- mediate) and what CAO (high, low, or intermediate) should be used for a high conversion to R. 11 12 из Па th Case (a) 1 1 1 1 (b) 1 2 1 1 (c) 2 1 1 1 (d) 1 2 (e) 1 (f) 1 02 21 1 0 2 1 1
