If the time elapsed is 4.26 min, what is the value of the rate constant, k?
ln[R]t / [R]o = -0.0237
I am not sure how to slove this. Is Rt 4.26 min?
To solve for the rate constant, k, using the given information, we need to understand the equation provided:
ln[R]t / [R]o = -0.0237
In this equation, [R]t refers to the concentration of the reactant at time t, and [R]o refers to the initial concentration of the reactant.
The value of t, in this case, is given as 4.26 min, so yes, Rt represents the concentration at that time.
To solve for k, we will rearrange the equation:
ln[R]t / [R]o = -k * t
Now, substitute the given values into the equation and solve for k:
-0.0237 = -k * 4.26
To isolate k, divide both sides of the equation by -4.26:
-0.0237 / -4.26 = k
Calculating the division, we find:
k ≈ 0.005571 (rounded to 6 decimal places)
Therefore, the approximate value of the rate constant, k, is 0.005571.
