WebOct 27, 2024 · Exercise 9.5. 1. Calculate the root-mean-square velocity for an oxygen molecule at –23 °C. Answer. If the temperature of a gas increases, its KE avg increases, more molecules have higher speeds and fewer molecules have lower speeds, and the distribution shifts toward higher speeds overall, that is, to the right. WebGeneral form of rate equation: Rate = k [A]2 or Rate = k[A]1[B]1 which has an overall order of two (second order). 4. Fractional orders are rare, but do exist! Recall our general rate expression: Rate = k[A]m[B]n If m = 0 ; reaction is zero order with respect to A If m = 1 ; reaction is 1st order with respect to A
