93. Consider the reaction
3 A+B+C ⟶ D+E
where the rate law is defined as
-Δ[A]/Δt = k[A]²[B][C]
An experiment is carried out where [B]₀=[C]₀=1.00 M and [A]₀=1.00 × 10-4 M.
a. If after 3.00 min,[A]=3.26 × 10-5 M, calculate the value of k.
Homework Answers
- Differential rate law and overall rate has different expressions for a chemical reaction.
- Differential rate law gives us the rate with respect to the appearance or dissappearance of any reactant/product.
- The whole differential rate is with respect to just one constituent of the equation and hence it is divided by its co-efficient to equate all the constituents.
- The overall rate expression cannot be formed just by looking at the equation. It has to be calculated using methods like steady-state approximation.
- The overall equation is not with respect to just one constituents.
