<prompt> All increase CO2 absorption in circuit except.Resistance in circuitHigh flowSmall granule sizeMedium granule size Chanelling  <response>: Factors that increase the rate of CO2 absorption are rate of flow of gas, granule size and channeling. The most common granule size used is 4 to 8 mesh units Channeling increases the surface area of granules that enables more CO2 absorption
