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.
If this is true we should stop using the word picnic, replacing it with outing or gathering. -- Sarah James, Baltimore, Maryland. A: Your question has several components; we will address each component. The etymology of the word picnic does not suggest racist or racial overtones. Picnic was originally a 17th Century French word, picque-nique. Its meaning was similar to today's meaning: a social gathering where each attendee brings a share of the food. The French piquer may have referred to a leisurely style of eating (pick at your food) or it may, simply, have meant, pick (pic).
