Question

A mixture 0. 500 mole of carbon monoxide and 0. 400 mole of bromine was placed into a rigid 1. 00 - L container and the system was allowed to come to equilibrium. The equilibrium concentration of COBr2 was 0. 233 M What is the value of K2 for this reaction? CO(g) + Br2(g) rightarrow Leftwards Arrow COBr2:(g) 5. 23 1. 22 1. 165 0. 858 0. 191 Benzocaine is from a family of chemicals that are good local anesthetics. Identify the functional group circled. aldehyde ketone ester carboxylic acid carbonyl

Explanation / Answer

Kc = 0.233/[(0.5-0.233)(0.4-0.233) Kc = 5.225 Hence, A 15. Ester as R-COO-R'
