標題[問題] 一題反應速率~
時間Tue Jul 20 21:40:29 2010
In the reaction,A=>Products
The initial concentration of A is 0.86M
and 40s later 0.78M
What is the initial rate of this reaction in M min^-1?
答案 1.2*10^-1
我代lnA=lnA0-kt
k=0.00225
然後r=k[A] 我算的事1.935*10^-3
感謝解答~"~ 最近一直麻煩大家

1F：→ z5137:先看單位→min-1，為0級反應，代公式 [A]=[A]o-Kt 07/20 21:44
2F：→ z5137:0.78=0.86-2/3t 乘除完為答案 07/20 21:45
3F：→ Epondo:是0級喔@@" 我一直以來都只看M^1-N 說... 07/20 21:50
4F：→ Epondo:對耶 是0級...0.0 07/20 21:50
