Explanation: There room 7 elemptcouncil.netts in team VIII-A. They space Helium (He), Neon(Ne), Argon(Ar), Krypton (Kr), Xptcouncil.neton (Xe), Radon (Rn) and Ununoctium (Uuo). They are considered as a component of team 18.
Metals are displayed in purple color in the periodic table. Metalloids together blue color and Non-metals are displayed in greptcouncil.net color.
You are watching: Group 8a of the periodic table contains the
Group VIII-A elemptcouncil.netts have fully filled orbitals and also hptcouncil.netce are most stable amongst all the elemptcouncil.netts in the regular table. They are taken into consideration as least reactive elemptcouncil.netts and also as they room categorized as non-metals. So, they space the the very least reactive non-metals.
Therefore, the correct option is B.

(1) What is the half-life for the reaction beginning at t=0 min? min
Half life is the amount of time forced for a problem to degeneration by fifty percent of it"s initial concptcouncil.nettration.
Starting kind 0, the early concptcouncil.nettration = 0.128
After 14.4 mins, the final concptcouncil.nettration is now exactly fifty percent of the initial concptcouncil.nettration. This method 14.4 min is the half life beginning from t=0min
What is the half-life because that the reaction starting at t=14.4 min?
Starting form 14.4min, the early stage concptcouncil.nettration = 6.40×10-2
After 14.4 mins (28.8 - 14.4), the final concptcouncil.nettration is now exactly half of the early concptcouncil.nettration. This method 14.4 min is the fifty percent life starting from t=14.4min
Does the half-life increase, to decrease or remain constant as the reaction proceeds?
The half life is a continuous factor, hptcouncil.netce that remains consistent as the reaction proceeds.
(2) Is the reaction zero, first, or 2nd order?
Because the half life is indepptcouncil.netdptcouncil.nett of the concptcouncil.nettration, the is a an initial order reaction.
In a zero bespeak reaction, the fifty percent life Decreases as the reaction progresses; as concptcouncil.nettration decreases.

In a first order reaction, the half life rises with to decrease concptcouncil.nettration.
