Half-Life 1st Order Reaction

[Olivia Young 1A]

Is the equation t1/2 = 0.693/k valid for all first order reactions? And if so, it it because the initial concentration of A cancel out and leave ln(1/2)?

[Dimitri Speron 1C]

Yes, that's exactly correct.

[Megan_Ervin_1F]

Also remember that you can always derive this equation it you have any doubts

[Erin Kim 2G]

For the first order
the half life equation is t(1/2)= ln2/k.
It is applicable to all first order rate reactions.

[Annalyn Diaz 1J]

Why is it that the half-life of a first order reaction doesn't depend on initial concentration?

[Nicholas Le 4H]

Yes, it is applicable to all first order rate reactions.

[Amy Dinh 1A]

The initial concentration gets cancelled out when you derive the equation. Thus you end up with the equation t1/2 = 0.693/k
