Consider this reaction: 2HI(g) --> H2 (g) +I2(g) At a certain temperature, it obeys this rate law. rate =(0.00468M^-1*s^-1)[HI]^2 Suppose a vessel contains a concentration

Consider this reaction: 2HI(g) --> H2 (g) +I2(g)

At a certain temperature, it obeys this rate law.

rate =(0.00468M^-1*s^-1)[HI]^2

Suppose a vessel contains a concentration of 0.760M. Calculate how long it takes for the concentration of HI to decrease to 23.0% of its initial value. You may assume no other reaction is important.

Round your answer to 2 significant digits.
