A chemical process is used to convet toulene (MW=92) and hydrogen to benzene (MW=78) and methane (CH4) by the reaction : Toulene+H2->Benzene+CH4
Two streams enter the process. The first input stream is pure liquid toulene, which enters at a rate of 40gmol/s. The second input stream is a mixture of H2 (95 mole%) and CH4 (5mole%). The flow rate of H2 in the second stream is equal to 200 gmol/s.
Two streams leave the process. The first output stream contains only liquid benzene (product) and toulene (uncoverted reactant). The second output stream gaseous H2 and CH4. If the concersion of toulene in the process is 75% (ie,. 25% id unreacted), what are the molar flow rate and mass fraction of benzene in the liquid output stream?
A beaker with 100 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 8.60 mL of a 0.380 HCl solution to the beaker. How much will the pH c..
