Answer:
Final [B] = 1.665 M
Explanation:
3A + 4B → C + 2D
Average rection rate = 3[A]/Δt = 4[B]/Δt = [C]/Δt = 2[D]/Δt
0.05600 M/s = 4 [B]/ 2.50 s
[B] = 0.035 M (concentration of B consumed)
Final [B] = initial [B] - consumed [B]
Final [B] = 1.700 M - 0.035 M
Final [B] = 1.665 M

Answer:-
(a) 3.5
(b) 3
Explanation:-
2KClO3 --> 2KCl + 3 O2
From the equation we see that 2 moles of KClO3 gives 2 moles of KCl.
So 3.5 moles of KClO3 will give 3 moles of KCl.
Again
3 moles of O2 are produced with 2 moles of KCl.
If 4.5 moles of O2 produced then
moles of KCl = 4.5 x 2/3
=3
