The initial rates listed in the table were determined for thethermal decomposition of azomethane (CH3N=NCH3):CH3N=NCH3 (g) → C2H6 (g) + N2 (g)Experiment Initial [CH3N=NCH3]MInitial rate of decompositionof [CH3N=NCH3] (M/s)1 2.4 x 10-2 6.0 x 10-62 8.0 x 10-3 2.0 x 10-6(a) What is the rate law? (2 mark)(b) What is the value of the rate constant for the decomposition reaction? (c) Calculate the percentage of azomethane that it will decomposein 10 minutes if the initial concentration of azomethane is equal to1.5×10-2M.
Assume that the heat required for the vaporization of the alcohol comes only from the aluminum block and that the alcohol vaporizes at 25.
250g of ice at 265K is mixed with 100g of water ar 305K. Calculate the final temperature of the mixture. Assume that no energy in the form of heat is transferred to the environment. (heat of fusion=300J/g; c(ice) =2.06J/g*K, c(water)=4.184J/g*K.
