The table gives net rate differences, defined as (Rate_forward − Rate_reverse), for the reaction E ⇌ F.
Time (s) | Net rate (mol·L⁻¹·s⁻¹)
0–10 | +0.52
10–20 | +0.34
20–30 | +0.18
30–40 | +0.06
40–50 | −0.04
50–60 | −0.12
During which 10-s interval did the reaction experience the greatest decrease in net rate toward products?
a) 40–50s
b) 10–20s
c) 0–10s
d) 20–30s
