Question

Consider the reaction C2H3Cl3 + 3H2 -> C2H6 + 3HCl

If the rate of formation of HCl is 25x10-6 gmol/g.cat-min

a) What is the rate of disappearance of trichloroethane?

b) What is the rate of formation of ethane?

I don't know what the unit of gmol/g.cat-min is. How specific is the unit in this question?

Answer 1

Rate of reaction is given by d (CH₂) -1 d (H₂) = 1 d (GH₂)=+1 d (HU) dt 3 dt Idt 3dt The rate of formation of Head (HCl) disappearance Cattle = -d (Cathely The rate of formation of of formation of H = + (SH) The rate of of

→ G H + 3HCl CH₂ cl + 3H₂ given 8 Rate of formation of formation of H 2 100 ml go tat-min (1) Rate 3 of disappearance of Coltells = 1 Rate of of the = 4(25x10 - 8.33 X10 great formation 3 -6 cat-min

(6) Rate of formation of feth Rate of ethane = 1 3 formation = // forma of He = (25/10-6) 8.33x 10-6 i mol 3 gmol cat-min go cat

> disapper talytic reaction, the rate disappearance fu expressed in the of species on per mats of units of g mole cat- min. and this is cataly Ito gmoleflitse-min.
