The reaction
CH3CH2N02 + 0H^- -----> CH3CHN02^- + H20
has the rate
r=k[CH3CH2N02][0H^-]
it takes 0.5 min for one % of CH3CH2N02 to react at 25 degrees C, in the case of a solution 0.002 M in CH3CH2N02 and 0.3 M in Na0H.
a) Calculate k.
b) Calculate also how long it would take for half of CH3CH2N02 to react.

Note. The 0H^- is just 0H negative and the same for the other compound.
