The number 0.750 was not used in my calculations for this problem. In Step 1, I used the value of (2), which is approximately 0.6931. This is a fundamental constant in the half-life formula for first-order reactions: t_1/2 = ((2))/(k) So, k = (0.6931)/(1670 s). Perhaps you are thinking of a different calculation or a different problem. Sometimes, in kinetics, if 75\% of a reactant has reacted, it means 25\% (or 0.25) remains. This would typically occur after two half-lives. However, in this problem, the time given (4710 s) is not exactly two half-lives (2 × 1670 s = 3340 s). The key values used were: • (2) ≈ 0.6931 • Half-life (t_1/2) = 1670 s • Time (t) = 4710 s That's 2 down. 3 left today — send the next one.
