Explanation:
Change in the concentration of reactant that is consumed in per unit time is known as rate of reaction.
The given chemical reaction will be written as follows.
Hence, rate law for the given reaction will be as follows.
Rate = k
where, k = rate constant
= initial pressure of the pollutant X
It is given that, = initial partial pressure of X = 0.473 atm
= final partial pressure of X = 0.376 atm
Time = 5.6 hours
Hence, formula for rate constant of first order reaction is as follows.
k =
=
= 0.041 per hour
Therefore, rate of decomposition will be calculated as follows.
Rate = = k
=
=
Thus, we can conclude that initial rate of decomposition of X is .
By Boyles Law (P1V1=P2V2), substituting values in and solving for V2, we find that the new volume is 3.6 L<span />
Planets outside solar system are referred to as exoplanets. some scientists have put forward suggestions that there could be living organisms residing in some of the exoplanets. scientists have suggested that some exoplanets are found within the habitable distance from the star they revolve around. at this distance temperature can allow existence of liquid water. Where there is water automatically there is life. so astronomers may infer that life exist in exoplanets by determining whether they are with habitable distance from their star.
