Write a matlab code to calculate and plot the second explosion limit (2k1=k9[m] for the H2- air mixture with Phi=0.5 within temperature range of 500-1000k compare the line with the explosion limit in the textbook and see if they qualitatively agree. Be careful with the units of the variables. Since the equation is non linear, you can use the f solve function in matlab or write simple iteration to solve the function. is you need to know any species properties, such as molecular weight etc, use the matlab toolbox.
