标题[化学] 问反应速率的问题
时间Thu Jul 3 15:07:35 2008
if the initial rate for the second-order reaction:2A→B is 1.0*10^-6 MS^-1
for [A]0= 0.01M at 25度C
a) what is the concentration of B after 10 minutes?
(已求出速率常数=0.01 半生期为10^8 s)
b) if the activation energy is 40KJmol^-1, what will be the initial rate
for the same reaction?(gas constant R=8.134JK^-1mol^-1)
这题我是这样算的: 因为知道上升十度C速率加快两倍 所以上升25度=加快4√2倍
所以温度上升後的初速率变成(1.0*10^-6)*4√2= 5.657*10^-6
不晓得我这样算对不对??请大大帮忙解答谢谢!!!!
