Methanol is synthesized commercially from co and h, by the reaction co+ 2hch oh over a cu/zno catalyst at -350°c at 50-100 atm. the standard- state thermodynamic data on this reaction are =-90.64 kj/mol and =-24.2kj/mol. (a) what is the equilibrium conversion of a stoichiometric mixture of co and h, to methanol at 298 k at 1 atm? (b) assuming ahr independent of t, what are ke and the equilibrium conversion at 1 atm and 350°c? (c) k., at 350°c is measured to be 1.94'104. how large is the error assuming constant ahr? (d) at what pressure will the equilibrium conversion be 50% at 350°c?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
