A tracer pulse response C(t) is a triangle: 0 at t=0, rising to 5 mol/L at t=2min, falling back to 0 at t=4min. The corresponding E(t) curve is correctly represented by which choice (peak value)?
- APeak E=0.25 min⁻¹ at t=2min
- BPeak Eθ=2.00 at θ=1
- Peak E=0.50 min⁻¹ at t=2min
- DPeak E=6.00 min⁻¹ at t=2min
Explanation
∫C(t)dt=area of triangle=0.5×4×5=10. E(t)=C(t)/10. Peak E at t=2: 5/10=0.5 min⁻¹.
