In earlier videos we see the rate law for a first-order reaction R=k [A], where [A] is the concentration of the reactant. If we were to increase or decrease this value, we see that R (the rate of the reaction) would increase or decrease as well. When dealing with half-life, however, we are working with k (the rate constant). teams and sfb calling

"WebAug 13, 2024 · The second half-life has an activity of half the previous count (not the initial count). Equation 11.2.1 can be used to calculate the amount of radioactivity remaining after a given time: N t = N 0 × ( 0.5) number of half-lives. where N t = activity at time t and N 0 = initial activity at time t = 0.

WebJan 10, 2024 · Half-life is defined as the time required for half of the unstable nuclei to undergo their decay process. Each substance has a different half-life. For example, carbon-10 has a half-life of only 19 … Webt = 120 seconds. Write the half-life equation and place the above values in that equation: T = 60 seconds. So, if an element with the initial value of 200 grams decayed to 50 grams in 120 seconds, its half-life will 60 seconds. Similarly, you can also calculate other parameters such as initial quantity, remaining quantity, and time by using the ...
