Part A. A certain first-order reaction (A→products) has a rate constant of 3.90×10−3 s−1 at 45 ∘C. How many minutes does it take for the concentration of the reactant, [A], to drop to 6.25% of the original concentration? Part B. A certain second-order reaction (B→products) has a rate constant of 1.90×10−3 M−1⋅s−1 at 27 ∘C and an initial half-life of 298 s . What is the concentration of the reactant B after one half-life?

The rate constant for a particular reaction that is 1st-order in N2O5 is 0.525 min–1. How much time will it take for the concentration of N2O5 to decrease to one-third its initial concentration? Make sure you pick an answer with the correct units. (Hint: Fora 1st-order reaction, the amount of time it takes to reduce a reactant's concentration to one-third is independent of the initial concentration of reactant.)

A certain first-order reaction has a rate constant of 1.65 min-1 at 20°C. What is the value of the rate constant at 60°C if the activation energy is 75.5 kJ/mol? The rate constant is 105 times bigger at 300 K than at 200K. Explain why reaction rate increases with temperature? At 227°C, the reaction: SO2Cl2(g) SO2(g) + Cl2(g), has an equilibrium constant of KC = 2.99×10-7. If a reaction mixture initially contains 0.175 M SO2Cl2, what is the equilibrium concentration...

For a first-order reaction, the half-life is constant. It depends only on the rate constant k k and not on the reactant concentration. It is expressed as t1/2=0.693k t 1 / 2 = 0.693 k For a second-order reaction, the half-life depends on the rate constant and the concentration of the reactant and so is expressed as t1/2=1k[A]0.
