intial concentration of [A) is the value at t=0s. (A)Calculate the values of the rate constant k msuming that the reaction is first erder. What is the value of k at 5c ? What is the value of k at 100 ? What is the value of k of is it? What is the value of i at 25s ? (b) Calculate the value of k atweming that the reaction is secend ortet. What is the value of k at 5s ? What is the value of k at 10o ? What is the value of k at is n ? What is the value of k at 25r ? (c) Use yeur renuls from parts A and n above to decise what the ender of the reaction in for your asea. (finter 1 or 2 ) (D) What is the concontrabon of (A) ar time thes a
