Question

Name: 10. Complete the following equations. Use the table of pKa value to decide where the equilibrium will be lie by determing Keq and whether there is a decrease or increase in free energy for each reaction. (each 2.5) (a) Li + pKa value CH2=CH2 44 PhCH3 (isopropyl)2NH38 NH CH3=CH-CH3 PhạCH HC=C-H CH3COCHE (CH3)3COH C2H5OH (RO2C)2CH2 13.5 C2H SH PhoH (b) CH3 = + NaNH2 16 (c) CF3COO + CH3COOH NHA (CH3)2NH*
hHow to handle this question ! plz help :)

Answer 1

A 4 YK a Maitym auid Base and . base o je obe Aequhz, Quu bnium w: be a direction in bodwand Bu-hi a strong base ltan diisopropy amide. The thee energy decaeases in the a deaction energy decaeases in the forward And @ Base B Cha-C=c-wet Paasha_ erkaca Na + NH3 1. ACID Base Base she equilibrium will be bavored in bon direction. Because Nanha is a strong base than soclium acetylice im. She bree enengy decreases in the forward reaction OH + base acid Cf3 couet CH3COOH = Base Acid eghe equilibrium will be bavoured in backward dinection because of cooh is a strong and than CHz Court the thee energy increases in Ite bod wald reaction
