Let G be a simple graph. G is said to be maximal planar if it is planar and the addition of any new edge to G results in a (simple) non-planar graph. Examples of maximal non-planar graphs are K4 , K5 minus an edge, and K3,3 minus an edge. (a) Show that a maximal planar graph is connected. (b) Show that a maximal planar graph of order ≥3 has no bridges. (c) Show that every face of a maximal planar...

For 2N2O5(g) = 4NO2(g) + O2(g) 1. Determine, by making the appropriate graphs, whether this decomposition reaction is zero, first, or second order with respect to N2O5 I found by makin the graph in excel that it was a first order reaction Now here are my questions 2. The stoichiometric coefficient for N205 in the reaction equation is 2. Depending on your answer to Problem 1, explain why the reaction order you obtained in Problem 1 is also 2, or explain...
