In a reaction, 2AtoProducts, the concentration of A decreases from 0.5" mol L"^(-1) to 0.4" mol L"^(-1) in 10 minutes. Calculate the rate during this interval. |
| Answer» Solution :Average rate `=-(1)/(2)(Delta[A])/(DELTAT)=-(1)/(2)([A]_(2)-[A_(1)])/(t_(2)-t_(1))=-(1)/(2)(0.4"M"-0.5" M")/(10" MIN")=-(1)/(2)(-0.1"M")/(10" min")=5XX10^(-3)" M min"^(-1).` | |
