What is the overall reaction order for the following rate law: Rate = k²

A reaction was shown to follow second-order kinetics. How much time is required for to change from 0.500 M to 0.250 M? (k = 0.456 M⁻¹ s⁻¹)

Match the slope of each line to the average, initial, or instantaneous reaction rate.

A reaction has a rate law of Rate = (1.25 M⁻²s⁻¹)². What concentration of would give the reaction a rate of 0.0891 M/s if the concentration of is 0.250 M?

The radioisotope ¹⁴C (half life = 5730 years) is used for carbon dating. What is the first order rate constant for ¹⁴C?
