In a reaction , 2A rarr products , 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((0.4M-0.5M)/(10MIN))=-1/2((-0.1M)/(10min))=5xx10^(-3) "M MIN"^(-1)` |
