Answer:
a) 6,7x10⁻⁴M/s
b) 8,0x10⁻⁴M/s
Explanation:
a) You can determine the average rate of descomposition calculating the ratio of change of concentration to change of time.
For the entire experiment:
t=0,00→ 0,0100M
t=10,00→0,0033M
= 6,7x10⁻⁴M/s
b) Between 2,00 and 4,00 seconds:
t=2,00→ 0,0071M
t=4,00→0,0055M
= 8,0x10⁻⁴M/s
I hope it helps!

The first solution or a I think is the correct answer
The number of mole of lithium, Li needed for the reaction is 3.2 moles (Option D)
<h3>Balanced equation </h3>
4Li + N₂(g) → 2Li₂N
From the balanced equation above,
2 moles of Li₂N were obtained from 4 moles of Li
<h3>How to determine the mole of lithium needed </h3>
From the balanced equation above,
2 moles of Li₂N were obtained from 4 moles of Li
Therefore,
1.6 moles of Li₂N will be obtained from = (1.6 × 4) / 2 = 3.2 moles of Li
Thus, 3.2 moles of Li are needed for the reaction
