The second order reaction for the decomposition of nitrosyl bromide has a half life of 12.5s at a concentration of 0.100M.
NOBr(g)-->NO(g) + 1/2Br2(g)
I need help finding k for the reaction, and how would I find how long it will take to decompose 80 % of a 0.0500M solution of nitrosyl bromide, and how fast 0.200M solution of nitrosyl bromide will decompose.© BrainMass Inc. brainmass.com September 26, 2018, 8:38 am ad1c9bdddf - https://brainmass.com/physics/half-life/zero-and-second-order-reaction-36367
For the second order reactions, you need the right formula
1/[At] - 1/[Ao] = kt
is the one you need to use.
Whenever they ask these types of questions, they usually give the half life of the reaction. Use the half life to find the k and then you are on the right track.
