Find the temperature at which Kp=41.0 for the reaction H2(g)+I2(g)<-->2HI(g). [Given: at 25 degrees C, for H2(g), deltaH degrees F=0, S degrees=131.0 J/mol*K; for I2(g), DeltaH degrees F=62.26 kJ/mol, S degrees=260.6 J/mol*K; for HI(g), DeltaH degrees F= 25.9 kJ/mol, S degrees=206.3 J/mol*K; assume that Delta H degrees and Delta S degrees are independent of temperature]A. 202KB. 1KC. 506KD. 498KE.1059K
To see the affect on W when n > N/2, calculate W for N = 20 and n = 9 and 11. Is the result at all surprising? Why? Can you explain why you get this result? What other choices of n would give similar results?
