The decomposition of formic acid follows first-order kinetics. HCO2H(g) → CO2(g) + H2(g) The half-life for the reaction at 550°C
FromTheMoon [43]

Answer:

Option 4 is correct (72 seconds)

Explanation:

Option 4 is correct (72 seconds)

The formula we are going to use is:

ln\frac{A}{A_o}=-kt

Where:

A is the final concentration

A_o is the initial concentration

k is the constant

t is the time

Half-Life=0.693/k

Half-life in our case=24 seconds

k=0.693/24

k=0.028875 s^-1

Since the concentration is decreased by 87.5 % which means only 12.5%(100-87.5%) is left.

The ratio A/A_o will become 0.125

ln 0.125=-0.028875*t\\t=72.015\ seconds

t≅ 72 seconds
