Example text

Loehmann From: I. M. , I hope that you can help with the following: When quinoline (C9H7N) is hydrogenated at about 350 °C over various heterogeneous catalysts, the three reactions shown below take place to varying extents. In one experiment in a batch reactor (closed system), the initial charge to the reactor was 100 mol of quinoline and 500 mol of hydrogen (H2). After 10 h, the reactor contents were analyzed, with the following results: Quinoline (C9H7N)-40 mol Hydrogen (H2)-290 mol Some data from one particular run are shown below.

Note that mi weight of "i". " For binary collisions of like molecules, say A with A, simply replace "B" with "N' in Eqn. (2-5) and divide the right-hand side by 2 to eliminate double counting of collisions. Collision theory predicts simple, power-law rate equations for reactions that result directly from binary collisions between molecules. In fact, CT predicts that the reaction rate will be first order in each of the colliding species. For a reaction between A and B, [_A

When N = 1, (kt/kr) = K£i. According to Eqn. " SOLUTION Applying Eqn. (2-18) with N set equal to 1 to Ch, CO, and COCh: CO : Ch : COCh (1/2) - 1 = -(1/2) 1 - (3/2) = -(1/2) vcoc1z = (1/2) - 0 = (1/2) vco = vc1z = : Therefore, the stoichiometric equation that will lead to the value of K£i that is equal to kt/kr is 1/2CO + 1/2Ch � 1/2C0Ch Part C: What is the value of APPROACH kr/kr (2-B) at 298 K? The equilibrium constant based on concentration for Reaction (2-B) at 298 K must be calculated, since we have shown that K£i is equal to kt/kr when the reaction is written with that stoichiometry.
