Give the units of the rate constants in terms of the power x in. M^x time-1 for reactions with the following overall orders. a) first order. b) 5/2 order. I know the units for the first order are. Mol L^-1 / s = k(mol L-1). K = s^-1. but in terms of what the question is asking, the x , I don't understand what they want...
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 \[k = 2.0\; M^{-2}\; sec^{-1}\]
