Answer: Li < Na < K is the answer
Explanation:
Answer:
Option A is correct.
Because two molecules of NO are consumed per molecule of O2, the rate of disappearance of O2(g) is 2.5×10−5 Ms−1.
Explanation:
2NO(g) + O2(g) → 2NO2(g)
The rate of a chemical reaction is defined as the amount of reactant used up or the amount of products formed in the reaction.
From the chemical balance, 2 moles of NO gives 1 mole of O2, hence, it is evident that 2 molecules of NO is consumed per 1 molecule of O2.
Hence, the rate of consumption of O2 is exactly half of the rate of consumption of NO.
Rate of consumption of O2 = (1/2) × Rate of consumption of NO = (1/2) × 5.0×10−5 Ms−1
= (2.5×10−5) Ms−1

B) 0.670 L ..............................
One of the clues are that there will be a change in temperature. Usually when a reaction takes place heat will be absorbed or released resulting in a change of temperature. Hope this helped!
