Homework Statement
Consider the following reaction
NOBr (g) → NO (g) + ½ Br2 (g)
The table below gives the time-dependent concentration of NOBr. Using this data,
determine, if the reaction is first- or second-order, with respect to NOBr. Give the rate
equation and determine the rate constant. To do this you’ll need to generate two plots,
and be sure to explain your reasoning. Then determine the half-live and lifetime for
NOBr. Watch your units! (7 marks)
t/s [NOBr]/mol dm-3
0.0 0.0250
6.2 0.0191
10.8 0.0162
14.7 0.0144
20.0 0.0125
24.6 0.011
Homework Equations
t1/2 = ln2/kr
The Attempt at a Solution
So I've been trying to work through this question for about an hour and a half and can't for the life of me figure out how to even start it off. I know I need to determine the order of the reaction first but can't even figure that out. If someone could give me two or three steps to get me going that would be great.
(I've made a graph of the time vs. concentration)
