Boltzmann constant k = 1. 3806488 10-23 m2 kg s-2 k-1. 1 meter = 1. 094 yards ; 1inch = 2. 54 centimeters. 1 (u. s) gallon = 3. 7854 liters; 1 atm = 760 mm hg = 760 torr = 101325 pa. R = 8. 314 j/mol. k = 0. 08205 l. atm/mol. k = 0. 08314 l. bar/mol. k. H = u + pv q = c. t; cs (h20) = 4. 18 j/g. c. S = k ln w ln k2/k1 = h /r (1/t1 1/t2) ph = -log[h+] ph + poh = 14. For the following compound (shown below) draw the structures of the conjugate base and the conjugate acid: (6 points) Ch2 ch2 cooh: at 327 c the equilibrium concentrations are [ch3oh] = 0. 25 m, [co] = 0. 40 m and [h2] = 1. 1 m for the conjugate base conjugate acid reaction. Calculate kp at this temperature (assume that the pressure is recorded in atm. )
