At a certain temperature the rate of this reaction is second order in H2CO3 with a rate constant of 4.5M-1s-1.
H2CO3 (aq) → H2O (aq) + CO2 (aq)
Suppose a vessel contains H2CO3 at a concentration of 0.800 M. Calculate how long it takes for the concentration of H2CO3 to decrease to 9.0% of its initial value. You may assume no other reaction is important.
