Question

Question 14 0.5 pts The molecular scene depicts a gaseous equilibrium mixture at 460°C for the reaction of H2 (blue) and 12 (purple) to form Hl. Each molecule represents 0.010 mol and the container volume is 1.0 L. (a) Is Kc>,=, or < 1? (enter>,=, or <) (b) Is Kp >, =, or <Kc? (enter>,=, or <) (c) Calculate AGºrxn (kJ/mol). (enter your number into 1 decimal place) (d) How would the value of AGºrxn change if the purple molecules represented H2 and the blue 12? (enter "i" for increase, 'd' for decrease or "dnc" for does not change>)
