A compound decomposes by a first order reaction. The concentration of the compound is 0.0250 M after 65 seconds when the initial concentration is 0.0350 M. What is the concentration of the compound after 1.47 minutes?
2 attempts left Check my work Enter your answer in the provided box. Many drugs decompose in blood by a first-order process. Two tablets of aspirin supply 0.60 g of the active compound. After 30 min, this compound reaches a maximum concentration of 2 mg/100 mL of blood. If the half-life for its breakdown is 90 min, what is its concentration (in mg/100 mL) 2.5 h after it reaches its maximum concentration? mg/100 mL
a compound decomposes by a first order process . if 36% of the compound decomposes in 60 minutes , the half life pf the compound is ? 38 -5 41 -18 93
A compound dissociates into its elements at 625 K in a first order process with a rate constant of 0.063s-1. If you start with a 0.26 M concentration of the compound at this temperature, what will the concentration be after 2.285s? (Assume that the compound is not reformed once it dissociates.) I am not sure how to solve it :(((( Please help me.
