Pleaseee answer BOTH parts (A&B)

Thank you,

Calculate reaction mass efficiency, mass productivity, mass intensity, and yield for Example 4.5, assuming that: (a) Both n-butanol and isobutanol are useful, salable products. (b) Only n-butanol is a usable, salable product. Example 4.5) Example 4.5 n-Butanol is obtained from hydroformylation reaction of propylene by the following reaction: CH3CH=CH2+CO+2H2CH3CH2CH2CH2OH Isobutanol is also produced in the process by means of CH3CH=CH2+CO+2H2CH3CH3CHCH2OH The process uses 609kg of propylene, 399kg/h of CO, and 58kg/h of H2 to produce 1000kg/h of 1000kg/h of 99% pure n-butanol and 50kg/h of 85% isobutanol. The process also requires 749MJ/h of electricity and 2270MJ/h of steam. What is the energy intensity of this process if the only useful product is the n-butanol? Solution Since in this case the only useful product is n-butanol, we have energyintensity=massofproducttotalprocessenergy=1000kg/h(749+2270)MJ/h=3.2MJ/kg Additional Points to Ponder How would this result change if isobutanol were also a usable product? If we wanted to evaluate the life cycle energy, which other energy requirements will need to be added for this process
