The answer is 60 minutes to complete 50% of reaction.
Explanation:
1 mole = 6.02 x 10^23 atoms (Avogadro’s number)
Step 1) Determine how many grams of a substance are in the problem
Step 2) Find the amount of grams in 1 mole of the substance
3) Multiply step one by step two
Explanation:
When atoms forms ion, they either lose or gain electrons.
In an atom, we have three subatomic particles;
- Protons are the positively charged particles
- Electrons are the negatively charged particles
- Neutrons carry no charges.
A neutral atom has equal number of protons and electrons.
A positively charged atom has more protons than electrons which implies that they have lost electrons.
A negatively charge atom has more electrons than protons suggesting that they have gained more electrons.
If we are given Na, it will for Na⁺ when it loses the electron in its outermost shell. Hence the number of protons is now more and the atoms is positively charged.

Answer:
Koverall [NO]^2 [Br2]
Balanced chemical reaction equation;
2NO + Br2 ⇄2NOBr
Explanation:
Consider the first step in the reaction;
NO(g) + Br2(g) ⇄ NOBr2(g) fast
The second step is the slower rate determining step
NOBr2(g) + NO(g) ⇄ 2NOBr(g)
Given that k1= [NOBr2]/[NO] [Br2]
k2= [NOBr2] [NO]
The concentration of the intermediate is now;
[NOBr2]= k1[NO][Br2]
It then follows that overall rate of reaction is
Rate= k1k2[NO]^2 [Br2]
Since k1k2=Koverall
Rate= Koverall [NO]^2 [Br2]
