Question

Jepet reaksioni: $$ \text{A}_{(g)} + \text{B}_{(g)} \rightarrow 2\text{C}_{(g)} $$ Përqendrimi fillestar i $\text{B}$ është: $$ [\text{B}]_0 = 0.8\ \text{mol} \cdot \text{l}^{-1} $$ Pas $30\ \text{s}$ harxhohet $60\%$ e substancës $\text{B}$. Sa është shpejtësia mesatare? A) $1.6 \times 10^{-1}\ \text{mol} \cdot \text{l}^{-1} \cdot \text{s}^{-1}$ B) $8 \times 10^{-3}\ \text{mol} \cdot \text{l}^{-1} \cdot \text{s}^{-1}$ C) $1.6 \times 10^{-2}\ \text{mol} \cdot \text{l}^{-1} \cdot \text{s}^{-1}$ D) $8 \times 10^{-2}\ \text{mol} \cdot \text{l}^{-1} \cdot \text{s}^{-1}$
