In our lecture videos, we discussed a communication model that is the most ethical and strategic for public relations. What is the best model that upholds our modern PR definitions?  

Using the chemical equilibria below,   N2(g) + O2(g)   ⇌  2 NO(g) K1    N2(g) + 3 H2(g)  ⇌   2 NH3(g) K2   H2(g) + 1/2 O2(g)   ⇌  H2O(g) K3 Determine the method used to calculate the equilibrium constant for the reaction shown below.   4 NH3(g) + 5 O2(g)  ⇌   4 NO(g) + 6 H2O(g) Kc  

According to collision theory, which condition(s) must be met in order for molecules to react? I. The reacting molecules must collide with enough energy to initiate the process of breaking and forming bonds. II. A catalyst must be in contact with the reacting molecules for a reaction to occur. III. The reacting molecules must collide with an orientation that can lead to rearrangement of the atoms.
