Please answer B-D! Will give thumbs up :)

The reactant concentration in a zero-order reaction was 0.100M after 180s and 3.00102M after 350s. 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. View Available Hint(s) Part B What was the initial reactant concentration for the reaction described in Part A? Express your answer with the appropriate units. Indicate the multiplication of units, as necessary, explicitly either with a multiplication dot or a dash. The reactant concentration in a first-order reaction was 7.60102M after 30.0s and 4.00103M after 90.0s. 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. Part D The reactant concentration in a second-order reaction was 0.560M after 240s and 7.40102M after 740s. 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
