We want to hydrolyze 500 lb per day of an ester at an initial concentration of 5 m (the ester has a molecular weight of 130) in aqueous basic solution in a batch process, and we need product that is 99% hydrolyzed. in benchtop experiments in a flask, we find that 50% of the ester hydrolyzes in 15 min for initial ester concentrations of either 1 or 5 m. we also find that, when we react for 8 h, all of the ester has hydrolyzed. it takes 1 h to empty the reactor and refill and heat it to start another batch. what size reactor will we need?

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
