WebSep 2, 2015 · What you've been given is simply the half-life ( t 1 / 2) of reactant A and the change in pressure of the reactant at some time after the reaction begins. That change in pressure is a fine proxy for concentration, since we are in the gas phase and are considering the change of one reactant only. WebIn one half-life (one minute in your example), each and every atom has a 50% chance of decaying. Now think of the atoms as dice. Each minute you throw the dice, and those that roll three or less you remove - they "decay". That means each dice has a 50% chance of being removed each minute. Thus, your dice have a half-life of one minute.
