At 400K oxalic acid decomposes according to the reaction: H2C2O4(g)CO2(g)+HCOOH(g) In three separate experiments, the intial pressure of oxalic acid and final total pressure after 20,000s is measured. Find the rate law of the reaction. Rate=3.06105s1PH2C2O4Rate=4.78105s1PH2C2 O4Rate=1.20105s1PH2C2O4Rate=7.17105s1PH2C2O4At 400K oxalic acid decomposes according to the reaction: H2C2O4(g)CO2(g)+HCOOH(g) In three separate experiments, the intial pressure of oxalic acid and final total pressure after 20,000s is measured.
