A platinum catalyst is used into vehicle catalytic converter to hasten the oxida

Question

A platinum catalyst is used into vehicle catalytic converter to hasten the oxidation of carbon monoxide:

                                                                                        Pt

                                                   2CO(g) + O2(g)                   2 CO2(g)           ?H = -566 kJ

Suppose you have a h reaction vessel containing an equilibrium mixture of the reactants an products. Under the following conditions, will the amount of carbon monoxide(CO) increase , decrease or stay the same?

a) A platinum catalyst is added                                           (circle:)   increase , decrease or stay the same

b) The temperature is increased                                          (circle:)   increase , decrease or stay the same

c) The pressure is increased by decreasing the volume (circle:)   increase , decrease or stay the same

d) The pressure is increased by adding argon gas            (circle:)   increase , decrease or stay the same

e) The pressure is increased by adding more oxygen      (circle: )   increase , decrease or stay the same

Please Explain why

Explanation / Answer

A will remain thes same as catalyst increases both forward and backward reaction

B as rection is exothermic reaction,the reaction will move reverse direction, converting products back to reactants. so CO ammount will increase

C will remain same

D will remain same

E decrease
