A scientist wants to look into the kinetics of the degradation of atrazine (A). There are 2 ways for degradation to occur. First, dealkylation to develop deisopropylatrazine (B) and deethylatrazine (C) with a kinetic constant of k1. Second, hydrolysis to create hydroxyatrazine (D) and N-isopropylammelide (E) with a kinetic constant k2. For all the mentioned species, derive their concentration profiles as a function of time when a batch reactor is utilized.
Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed antidepressants. SSRIs block the reabsorption of the neurotransmitter serotonin in the brain. Changing the balance of serotonin helps brain cells send and receive chemical messages, which in turn boosts mood. Two SSRI medications are Faverin (fluvoxamine, C15H21F3N2O2 ) and Zoloft (sertraline, C17H17Cl2N ). Determine the molar masses of Faverin and Zoloft
