Therefore, the rate law is \[r =2.0[A][B]^2\] The order of the reaction with respect to A is 1 and with respect to B is 2; the overall reaction order is as follows: 1 + 2 = 3. To calculate k, substitute the values from any one of the above trials into the rate law: 2.0 M/sec = k(1.00 M)(1.00M) 2 \[k = 2.0\; M^{-2}\; sec^{-1}\]
This one, however, is bullshit. According to Snopes.com, the word picnic actually derives from the totally innocuous French word piquenique. The other, horrible meaning of the word is found nowhere outside of that one idiotic email forward. So it was never a euphemism for anything. Or even a real phrase.
Picnic: The word picnic did not originate as an abbreviation of pick a nigger, a phrase falsely claimed to have been used by white families at community lynchings in the 19th century. Picnic comes from 17th-century French piquenique, which is of uncertain origin.
