(Solved): The rate constant for the following reaction is 0.0620M1s1. Aproductsrate=k\[A]2 ...

The rate constant for the following reaction is $$0.0620{\mathrm{M}}^{?1}?{\mathrm{s}}^{?1}$$. $$A?\text{ products rate }=k\backslash [A{]}^2$$ 1. How long, in seconds, would it take for the concentration of A to decrease from $$0.690\mathrm{M}$$ to $$0.400\mathrm{M}$$ ? Express your answer to 3 sig figs and do not include units in your response. Answer: Blank $$1\mathrm{s}$$ 2. If the initial concentration of A was $$8.55\mathrm{M}$$, what will the concentration be after $$0.105\min$$ ? Express your answer to 3 sig figs and do not include units in your response. Answer: Blank $$2\mathrm{M}$$ 3. How long, in minutes, would it take for $$80\%$$ of A to be consumed if you started with a $$1.00$$ M solution of A? Express your answer to 3 sig figs and do not include units in your response. Answer: Blank $$3\min$$
