For the reaction CH4 (g) + N2 (g) + 164 kJ 6 HCN(g) + NH3 (g) at 25degrees C and 1 atm of pressure ÄGo = 159 kJ. Calculate ÄSo at 25degrees C. ÄHfo for CH4 (g) = -74.77 kJ/mol and ÄHfo for NH3 (g) = -46.09 kJ/mol. What is ÄHfo for HCN(g) ?
Bond strengths and bond types for various zinc compounds.
Hello: We have homework that asks us to find the bond strength and identify the type of bond (ionic, covalent etc) for the following zinc compounds: zinc chloride zinc phosphate zinc carbonate zinc hydroxide zinc oxide zinc sulfate zinc oxalate
Reaction Kinetics, Rate Laws and Equilibrium
1. The isomerization of cyclopropane to form propene CH3 - CH CH2CH2 is a first-order reaction. At 760 K, 15 percent of a sample of cyclopropane changes to propene in 6.8 minutes. What is the half-life of cyclopropane at 760 K? 2. Consider the two gaseous equilibria (K1 and K2): SO2(g) + ½O2(g) SO3(g) K ...continues
1) The Equilibrium constant Kp for the reaction 2SO2(g) + O2(g) --- 2SO3(g) Is 5.60 x 10^4 at 350 degrees C. The initial pressures of SO2 is 0.350 atm and the initial pressure of O2 is 0.762 atm at 350 degrees C. When a mixture equillibtrates, is the total pressure less than or greater than the sum of the in ...continues
