Title: Half-life of the reaction
Post by: Nathaniel on March 15, 2008, 10:32:55 PM

The decay constant for a reaction is 2.34 x 10^-3/s

What is the half-life of the reaction (answer tothe nearest second)?


Can someone please tell me where I went wrong?

Halflife = 0.693 / k

k = decay constant

Halflife = 0.693 / 2.34 x 10^-3/s

= 2.96

= 3 seconds

Why was I wrong?
