The decomposition reaction of hydrogen peroxide:
2 H₂O₂(aq) → 2 H₂O(l) + O₂(g)
The order of reaction is : first order reaction.
[H₂O₂]₀ = 12 M at time = 0
[H₂O₂] = 9.5 M at time = 30 minutes
Average reaction rate = - (Δ[reactants] / Δt)
= - (final reactants conc. - initial reactants conc.) / Δt
= - (9.5 M -12 M) / (30 min - 0 min)
= 0.083 mol / L.min
Can I know which grade are uh, according to the grade only visible to check
I think so, <span> how much of all chemistry is to do with numbers? A lot! So being good at mathematics makes a huge aspect of chemistry so much easier but if you aren't mathematical then you can work at it and become reasonably proficient at it.</span>
