              \mathrm{A(g)+2B(g)\longrightarrow C(g)+D(g)}
\mathrm{t= 0 \quad 0.80\quad 0.10}                   -              -
\mathrm{t= t \quad 0.56\quad 0.52 \quad 0.24 \quad 0.24}

\mathrm{R=k P_{A} \times P_{B}^{2}=k \times 0.8 \times(0.1)^{2}}
\mathrm{R^{\prime}=K P_{A} \times P_{B}^{2}=k \times 0.56 \times(0.52)^{2}}
\mathrm{\frac{R^{\prime}}{R}=\frac{k \times 0.8 \times(0.1)^{2}}{k \times 0.56 \times(0.52)^{2}}=\frac{1}{18.9}=\approx \frac{1}{20}}.
