Problem

The reaction

2\,\text{A} \rightarrow 3\,\text{B}

is carried out in solution. The concentration of A decreases from

0.500\,\text{M}

0.350\,\text{M}

over a 25 s interval, and no B is present initially. What is the concentration of B after 25 s? a)

0.150\,\text{M}

0.300\,\text{M}

0.225\,\text{M}

0.175\,\text{M}
