transition metals

Question 1

what are the reactions for the contact process

Answer 1

SO2 + V2O5 -> SO3 + V2O4
2V2O4 + O2 -> 2V2O5

Question 2

what are the reactions that take place when Fe acts as a homogeneous catalyst

Answer 2

S2O8^2- + 2Fe2+ -> 2SO4^2- + 2Fe3+
2Fe3+ + 2I- -> 2Fe2+ + I2

Question 3

what is the autocatalysis reaction when Mn2+ acts as the catalyst

Answer 3

2MnO4- + 16H+ + 5C2O4^2- -> 2Mn2+ + 8H2O + 10CO2

Question 4

what are the redox titration reaction

Answer 4

MnO4- + 8H+ +5e- -> Mn2+ +4H2O

Fe2+ -> Fe3+ + e-

C2O4^2- -> 2CO2 + 2e-
