The gaseous explosive reaction at constant pressure : the reaction order and reaction rate
A 1931 technical report from NASA's Technical Reports Server, a scientific paper on the kinetics of gaseous explosive reactions at constant pressure, with its reaction order and rate worked out through experiment. The pictures are plotted graphs of speed in cm per second against concentration fractions, each showing a measured data scatter around a smooth bell-shaped curve that rises to a peak and falls away to zero. A designer might take from them the clean, sparse look of early scientific chart work: fine grid lines, dotted data points, and a single bold curve.
