Hi, so to solve for this, we will use the formula for first order reaction.
00:05
Y, the remaining amount, is equivalent to y0, the initial amount, multiplied by e, raised to the power of negative k, the rate constant, and then t, the time elapsed.
00:14
So our unknown here is y, the remaining amount.
00:18
So let's plug in the information that we have.
00:20
The initial concentration is 0 .600 molar multiplied by e, raised to the power of the rate constant, 0 .00620 per second, and then the time elapsed, we have 85 seconds.
00:35
So that means we could cancel the unit in...
