Question

For the reaction, CO + 2H2 =CH3OH. If active mass of CO is kept constant and active mass of H2 is tripled, the rate of reaction will be

Answer 1

hope it helps....you

Answer 2

active mass=no. of moles/concentration

Kc ={ch3oh}/{co}[H2]2

After tripling the active mass of H2,

conc=no. of moles/3.active mass

=[H2]/3

Kc' = [ch3oh]/[co][H2/3]2

=9.[ch3oh]/[co][H2]

Kc'=9Kc
