Answer:
(D) K >> 1 implies that the reaction is very fast at producing products.
Explanation:
For a reaction:
nA + xB ⇄ bC + aD
The thermodynamic equilibrium constant (k) is:
k = <em>(1)</em>
(A) When K >> 1, the forward reaction is favored and essentially goes to completion. <em>TRUE. </em>By (1), a k>> 1 means that you have more products than reactants
(B) When K << 1, the reverse reaction is favored and the forward reaction does not proceed to a great extent. <em>TRUE. </em>By (1), a k<< 1 means that you have more reactants than products.
(C) When K ≈ 1, neither the forward or reverse reaction is strongly favored, and about the same amount of reactants and products exist at equilibrium. <em>TRUE. </em>By (1), a k ≈ 1 means that you have the same concentration of products andreactants
(D) K >> 1 implies that the reaction is very fast at producing products. <em>FALSE. </em>k is a thermodynamic parameter. To evaluate the rate of a reaction you need to study the kinetics of this one.

464 g radioisotope was present when the sample was put in storage
<h3>Further explanation</h3>Given
Sample waste of Co-60 = 14.5 g
26.5 years in storage
Required
Initial sample
Solution
General formulas used in decay:
t = duration of decay
t 1/2 = half-life
N₀ = the number of initial radioactive atoms
Nt = the number of radioactive atoms left after decaying during T time
Half-life of Co-60 = 5.3 years
Input the value :
