Dear â€‹Benedict
William,

2 moles of acetic acid is present in 1 litre while 3 moles of ethanol are present in 1 litre
So the rate ffor the reaction is2CH3COOH + 3C2H5OH→2CH3COOC2H5 + 2H2O + C2H5OHrate=k(Conc
CH3COOH)2 (Conc
C2H5OH)3orrate(r1)=k (mole/litre)2 (mole/litre)3r1=k2233r1=k 108if both reactants are diluted with equal volume (V) then total volume will be 2V for each reactantso new rate (r2) will be r2=k2/223/23=k274so r2r1=274×108or r2=116r1 so the decrease in rate will be 116  w
r t  the initial rate
