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.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the answer is minerals.
