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.
Word Origin and History for hazard Expand. n. c.1300, from Old French hasard, hasart (12c.) game of chance played with dice, possibly from Spanish azar an unfortunate card or throw at dice, which is said to be from Arabic az-zahr (for al-zahr) the die.. But this is doubtful because of the absence of zahr in classical Arabic dictionaries. Klein suggests Arabic yasara he played at dice; Arabic -s- regularly becomes Spanish -z-. The -d was added in French in confusion with the native suffix -ard. In English, sense of chance of loss or harm, risk first recorded 1540s.
