2 HgCl2(aq) + C2O42-(aq) 2 Cl-(aq) + 2 CO2(g) + Hg2Cl2(s)
The rate law for this reaction is:
Rate = k [HgCl2(aq)] [C2O42-(aq)]2
At a certain temperature when [HgCl2(aq)] = 0.122 M and[C2O42-(aq)] = 0.169 M, the rate of this reaction is 4.88e-05 Ms-1. What is the reaction rate when the concentration of C2O42-(aq)is doubled, to 0.338 M, while the concentration of HgCl2(aq) is0.122 M?
a) The reaction rate is 3.90e-04 M s-1.
b) The reaction rate is 1.95e-04 M s-1.
c) The reaction rate is 2.44e-05 M s-1.
d) The reaction rate is 3.50e-03 M s-1.
e) The reaction rate is 1.40e-02 M s-1.
