six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium, and astatine.
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 .
