Question

When formic acid is heated, it decomposes to hydrogen and carbon dioxide in a first-order decay:

HCOOH(g) ?CO2(g) + H2 (g)

The rate of reaction is monitored by measuring the total pressure in the reaction container.

Time (s) . . . P (torr)
0 . . . . . . . . . 220
50 . . . . . . . . 324
100 . . . . . . . 379
150 . . . . . . . 408
200 . . . . . . . 423
250 . . . . . . . 431
300 . . . . . . . 435

At the start of the reaction (time = 0), only formic acid is present. What is the formic acid pressure (in torr) when the total pressure is 243? Hint: use Dalton's law of partial pressure and the reaction stoichiometry. Answer: Correct Marks for this submission: 1/1. Question18 Marks: 1
What is the rate constant (in s-1)? (To deternime the rate, you must use a reactant concentration or pressure.

Explanation / Answer

K*t=Ln(Pinf-Pini /Pinf-Pt)
WHERE
Pinf=TOTAL PRESSURE AT INFINITY
Pini=TOTAL PRESSURE AT TIME T=0
Pt =TOTAL PRESSURE AT TIME T=t
