URGENT, PLEASE HELP. I WILL UPVOTE IF CORRECT. THANK YOU!

The reactant concentration in a first-order reaction was 7.90102M after 10.0s and 1.80103M after 80.0s. 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. 2 Incorrect; Try Again; 5 attempts remaining Part D The reactant concentration in a second-order reaction was 0.720M after 165s and 1.40102M after 700s.
