For the \(\mathrm{CO}_{2}\) absorption in \(\mathrm{NaOH}\) problem in the text, examine the effects of (i) changing the partial pressure of \(\mathrm{CO}_{2}\) and (ii) the concentration of the liquid-phase reactant. State the range of conditions under which the reaction is expected to take place under pseudo-first-order conditions. State the conditions under which the reaction can be treated as instantaneous.

Find the conditions (partial pressure of \(\mathrm{CO}_{2}\) ) for which the reaction becomes instantaneous. Find the rate under this condition.

Find the conditions (partial pressure of \(\mathrm{CO}_{2}\) ) for which reaction occurs under pseudofirst-order conditions, i.e., the interfacial concentration of B is nearly the same as the bulk concentration. Find the rate under this condition.
