hydrolysis of ester
« on: January 04, 2016, 01:18:34 AM »
RCOOCH3(aq) + H2O(l)
𝐻+
→ RCOOH(aq) +CH3OH(aq)

The rate of the reaction is given by the rate law:
Rate =k [H+] [RCOOCH3]


the question asked if the rate of the reaction will increase, decrease or remain the same when water is added to the mixture
i thought it is unchanged as water isn't included in the rate law,but the answer is decrease so I want to know why is that

urgent!!thanks

What does [H+]·[RCOOCH3] mean?

i don't understand what do you mean

[H+]·[RCOOCH3] are the substances included in the rate equation which are first order

How then do you convert these substances into something relating to the rate of the reaction?
