Week 4 Question 1


4 NH3(g)  + 5 O2(g)   --->   4 NO(g)  +  6 H2O(l)

I will write a question based upon rates of the above reaction. The first person will answer this question and then write a second question that the next person will answer and then write a question continuing on …..

So to start: What is the expression for the rate of disappearance of NH3?

  1. avg. rate[NH3] = -(∆[NH3])/∆t

    2H2S + 3O2 --> 2H2O + 2SO2

    What are the relationships between all species?

  2. 1/2 -(∆[H2S]/∆t) = 1/3 -(∆[O2]/∆t) = 1/2 (∆H2O/∆t) = 1/2 (∆SO2/∆t)

    What are the four factors that affect the rate of a reaction?

  3. 1.)concentration of reactiants
    2.)temperature of the Reactions mixture
    3.)Catalyst
    4.)Phase of the reaction

    CHCl3 + Cl2 --> CCl4 + HCl
    what is the rate of appearance of CCl4 in this reaction?

  4. rate of appearance of CCl₄ = ∆[CCl₄]/∆t

    Thanks for your responses!
