3.7. methanol is synthesized commercially from co and h2 by the reaction co+ 2h2 ch2oh 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 h2 to methanol at 298 k at 1 atm? (b) assuming ahg independent of t, what are keq and the equilibrium conversion at 1 atm and 350°c? (c) kg at 350°c is measured to be 1.94104. how large is the error assuming constant ahr? (d) at what pressure will the equilibrium conversion be 50% at 350°c?
