| X_absorption {isogeochem} | R Documentation |
Relative rates of CO2 absorption reactions
Description
X_absorption() calculates the relative abundance of the DIC species
as a function of solution temperature, pH, and salinity.
Usage
X_absorption(temp, pH, S)
Arguments
temp |
The temperature of the solution (°C). |
pH |
The pH of the solution. |
S |
The salinity of the solution (g/kg or ‰). |
Details
X_hydration = ((kCO2 / (kCO2 + kOHxKw / aH)) * 100), where
kCO2 is the rate constant for CO2 hydration from Johnson (1982)
kOHxKw is the rate constant for CO2 hydroxylation x Kw from Schulz et al. (2006).
aH is 10^(-pH)
Value
Returns a data frame with the relative rates of CO2 absorption reactions:
Relative rate of CO2 hydration (%).
Relative rate of CO2 hydroxylation (%).
