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.

Would I do ln 4.26 min X -0.0237?

To determine the value of the rate constant, k, you need to rearrange the given equation:

ln[R]t / [R]o = -k * t

Given that the time elapsed, t, is 4.26 min and ln[R]t / [R]o is -0.0237, you can substitute these values into the equation as follows:

-0.0237 = -k * 4.26

To solve for k, divide both sides of the equation by -4.26:

k = (-0.0237) / (-4.26)

Simplifying the right side of the equation gives you:

k = 0.00556

Therefore, the value of the rate constant, k, is approximately 0.00556.
