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.
1620s, originally a seamen's term, probably from Dutch plug, Middle Dutch plugge bung, stopper, related to Norwegian plugg, Danish plÃ¸g, North Frisian plaak, Middle Low German pluck, German Pflock; ultimate origin uncertain. Irish and Gaelic words are from English.
