a) The reactant concentration in a zero-order reaction was 8.0010² MM after 150 s and 1.0010² MM after 330 s . What is the rate constant for this reaction?

Express your answer with the appropriate units. Indicate the multiplication of units, as necessary, explicitly either with a multiplication dot or a dash.

c)

The reactant concentration in a first-order reaction was 7.4010² MM after 35.0 ss and 2.7010³ MM after 75.0 ss . What is the rate constant for this reaction?

Express your answer with the appropriate units. Indicate the multiplication of units, as necessary, explicitly either with a multiplication dot or a dash.

d)

The reactant concentration in a second-order reaction was 0.500 MM after 135 ss and 1.6010² MM after 880 ss . What is the rate constant for this reaction?

Express your answer with the appropriate units. Indicate the multiplication of units, as necessary, explicitly either with a multiplication dot or a dash.
