Part A
At 400 K oxalic acid decomposes according to the reaction:
H_C,Oí(g)→CO,(g)+HCOOH(g)
In three separate experiments, the intial pressure of oxalic acid and final total pressure after 20,000 s is measured.
1 2 3
65.8 92.1 111
106 149 179
Experiment
PH₂C₂O4 at t=0
Protal at t=20,000 s
Find the rate law of the reaction.
Rate=3.06x10-58-¹PH,C₂0.
Rate 4.78x10-5¹PH₂C₂O
Rate 1.20x10-5s ¹PH₂C₂0
Rate 7.17x10-5s ¹PH₂C₂0.
