At 400 K 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 20,000 s is measured.

Find the rate law of the reaction.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

50.23 i believe is correct but don't quote me on that.
