if a reactant has a half life of 20 minutes, what percentage of it will remain...
C-11 has a half-life of 20.3 minutes. What percentage of a C-11 sample will remain after 1 hour?
What percentage of reactant will remains after 120 s if the half-life is 60 s?
The half-life of a reaction, t1/2, is the time it takes for the reactant concentration [A] to decrease by half. For example, after one half-life the concentration falls from the initial concentration [A]0 to [A]0/2, after a second half-life to [A]0/4, after a third half-life to [A]0/8, and so on. on. For a first-order reaction, the half-life is constant. It depends only on the rate constant k and not on the reactant concentration. It is expressed as t1/2=0.693k For a...
A decomposition reaction has a rate constant of 0.0012 yr?^-1 (a) What is the half-life of the reaction? (b) How long does it take for [reactant] to reach 12.5% of its original value? Please explain step by step, I am confused on how to solve part B mostly! How do you rearrange the formulas to get the answer??
+ Half-life for First and Second Order Reactions 11 of 11 The half-life of a reaction, t1/2, is the time it takes for the reactant concentration A to decrease by half. For example, after one half-Me the concentration falls from the initial concentration (Alo to A\o/2, after a second half-life to Alo/4 after a third half-life to A./8, and so on. on Review Constants Periodic Table 11/25 For a second-order reaction, the half-life depends on the rate constant and the...
What is the concentration of a reactant after 30 minutes, given the initial concentration is 0.10M. The reaction is a first order reaction with a half-life of 75 minutes.
1. A certain first order reaction has a rate constant of 0.036 min-1. How much of the reactant will remain if the reaction is run for 2.5 hours and the initial concentration of the reactant is 0.31 M? 2. A certain first order reaction has a rate constant of 0.036 min-1. How much of the reactant will remain if the reaction is run for 2.5 hours and the initial concentration of the reactant is 0.31 M? 3. The rate constant...
A first order reaction has a half-life of 196 seconds at 25oC. How long (in minutes) does it take for the concentration of the reactant to drop to 3.125% of the original concentration? (it's not 16.34) The rate constant of a chemical reaction increased from 0.197 s-1 to 3.24 s-1 after raising the temperature from 20.0 oC to 60.0 oC. What is the activation energy (in kJ/mol) for this reaction? (Hint: Think about what R value to use and what...
