Problem
Rates for the decomposition of X₂(g) to 2X(g) were measured at three times.
Time (s) | Rate_fwd (M·s⁻¹) | Rate_rev (M·s⁻¹)
10 | 9.0×10−4 | 2.0×10−4
30 | 6.0×10−4 | 5.5×10−4
50 | 4.5×10−4 | 4.5×10−4
Write, in order and separated by commas, the net direction of change at 10 s, 30 s, and 50 s (use “products,” “reactants,” or “none”).
