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?

What amount of time is required for the concentration of A to decrease from 0.800 M to 0.200 M in the zero-order reaction A → B? (k = 0.0567 M*s⁻¹)

What is the order of the reaction A → B given the plot shown?

How many mL of 0.235M of NaOH(aq) is required to titrate (completely neutralize) 35.0 mL of 0.125M H3PO4(aq)?                        3 NaOH (aq)  +    H3PO4 (aq)  →    Na3PO4  (aq)   +  3 H2O  (l)     Mark your answer next to words “Final answer is”.
