Half order reaction rate

WebConsider a third order reaction with the rate law rate = k[A]²[B]. If B is in very large excess, the concentration of B will change very little as A gets used up. ... For a first order reaction we saw that the half-life was constant but here the half-life isn't constant because the half-life depends on the initial concentration of A. Now let's ... WebZero order reaction simply means that the rate of reaction is independent of concentration of reactants. And if you put a substance in a box then the change in its area will be negligibly small compared to the amount of gas evolved. for example if there is 1 mole of dry ice aka solid CO2 and 0.1 mole of it sublimes then evolved CO2 will have huge 2.27 litres …
