Problem

For the reaction 3A(g) + 2B(g) → 5C(g), the concentration of A decreases at a rate of 0.015 mol·L⁻¹·s⁻¹. What is the corresponding rate of appearance of C? (a) 0.015  mol L−1 s−10.015\;\text{mol}\,\text{L}^{-1}\,\text{s}^{-1} (b) 0.025  mol L−1 s−10.025\;\text{mol}\,\text{L}^{-1}\,\text{s}^{-1} (c) 0.0090  mol L−1 s−10.0090\;\text{mol}\,\text{L}^{-1}\,\text{s}^{-1} (d) 0.0050  mol L−1 s−10.0050\;\text{mol}\,\text{L}^{-1}\,\text{s}^{-1}
