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.
You'll be heartened to know 'picnic' has nothing to do with crowds gathering to witness the lynching of blacks (or anyone else, for that matter) in America. 'Picnic' began life as a 17th-century French word: it wasn't even close to being an American invention. A 1692 edition of Origines de la Langue FranÃ§oise de MÃ©nage. mentions 'piquenique' as being of recent origin and marks the first appearance of the word in print.
