. At 25cC, gaseous dinitrogen pentoxide decomposes into the gaseous products nitrogen dioxide and oxygen. The product nitrogen dioxide has a reddish-brown color while both dinitrogen pentoxide and oxygen gases are colorless. The progress of the reaction can be followed by measuring the absorbance as the reddish-brown product accumulates. (a) Write a balanced net ionic equation with lowest whole number coefficients to describe the decomposition. (b) The reaction is found to be first-order. Which function of [N2O5] would give a straight line if plotted against time t
