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

At a certain temperature it obeys this rate law.

Rate= 8.74 x 10^-4 s^1

Suppose a vessel contains HI at a concentration of 0.330M. Calculate the concentration of HI in the vessel 800 seconds later. You may assume no other reaction is important. Round your answer to significant digit

Explanation:

Hello,

In this case, based on the given units of the rate constant, it is a first-order reaction with respect to HI, therefore, the rate law is:

Whose integration turns out:

Therefore, the concentration of HI after 800 second finally result:

Best regards.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

the answer is c i took the test
