Considered first is a single diffusing reactant undergoing an irreversible reaction upon first encounter with a stationary co-reactant [\"one-walker (1W) problem\"]. We then generalize this scenario to allow for a competing reaction, i.e., instantaneous trapping of the diffusing reactant with probability $s$ at any vacant site before interacting with a (stationary) co-reactant at a target site. We determine the mean walklength of the diffusing reactant until irreversible reaction occurs.
