Answer:
D. 2.5 × 10–4 M
Explanation:
Data given in the question are;
rate constant of 5.0 × 10–2 mol/L·s
[A]0 = 1.0 × 10–3 M
5 × 10–3 sec
It was mentioned that the reaction is a zero order reaction. One interesting charaacteristics about zero order reactio is that the rate of reaction is indepenedent on the concentrations of the reactants.
This means in zero order reactions, we have;
Rate = Rate constant
Rate = 5.0 × 10–2 mol/L·s
What is the concentration of B after 5 × 10–3 sec?
Concentration = Rate * Time
Concentration = 5.0 × 10–2 * 5 × 10–3
Concentration = 2.5 × 10–4 M
Correct option = D
Answer:
the series circuit has <u>one current</u> so if you don't disconnect the wires nothing happens
but if you disconnect the wires in series circuit, the current stop and the current doesn't go to the end

The volume occupied by the gas in the container is 1 m³
Boyles law applies
P₁ V₁ = P₂ V₂
Where P₁ = 200kpa
P₂ = 300kpa
if its initial volume is 1.5
then,
P₁ V₁ = P₂ V₂
200 × 1.5 = 300 × V₂
V₂ = 200 × 1.5 / 300
= 1 m³
Hence the volume occupied by the gas container is 1 m³
