While the slope of the rising edge of the peak remains unaffected by the changing pressure, the descend edge flattens at lower pressures, indicating a reduced sorption rate at lower partial pressures and a consequently slower saturation of the sorbent. Figure further shows the corresponding sorption capacities 𝑞 obtained by integration of the extents of sorption. Comparing values at equal temperatures, the higher partial pressure of NH3 increases the sorption capacity. Yet, the maximum capacity was measured at a temperature of 350 °C, even though this temperature does not represent the experiment with the highest partial pressure.
