The reaction between ethyl bromide (C2H5Br) and hydroxide ion in ethyl alcohol at 330 K, C2H5BR(alc) + OH-(alc) --> C2H5OH(l) + Br-(alc), is first order each in ethyl bromide and hydroxide ion. When [C2H5Br] is 0.0477 M and [OH-] is 0.100 M, the rate of disappearance of ethyl bromide is 1.7 x 10^-7 M/s.
A mixture containing 2.01 g each of CH4(g), C2H4(g) and C4H10(g) is contained in a 1.50 L flask at a temperature of 25°C. (a) Calculate the partial pressure of each of the gases in the mixture.
Until 200 yr ago, manufactured iron contained charcoal produced from freshly cut wood that was added during the smelting process. As a result of this practice, older samples of iron can be dated accurately using the carbon-14 method
The second-order reaction 2 Mn(CO)5 Mn2(CO)10, has a rate constant equal to 3.0 x 10^9 M-1 s-1 at 25C. If the initial concentration of Mn(CO)5 is 2.0 x 10-5 M, how long will it take for 90.% of the reactant to disappear?
