The second-order rate constant for the reaction ch3cooc2h5(aq)+oh−(aq)→ch3co2−(aq)+ ch3ch2oh(aq)is 0.11 dm3mol−1s−1. what is the concentration of ester after (a) 10 s, (b) 10 min when ethyl acetate is added to sodium hydroxide so that the initial concentrations are [naoh] =0.050 mol dm−3and [ch3cooc2h5]=0.100 mol dm−3?

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

the answer is 0.8m.
