The reaction takes place in 1.00 L. a. Express the rate of the reaction as a function of the rates of appearance and disappearance of A and C. b. Find the initial rate of the reaction. Experimental data are expressed in the table below. t (s) [A], M 0.00 4.20 10.0 3.20 20.0 2.45 30.0 1.87 40.0 1.42 50.0 1.09 *c. Determine the order of the reaction. Is the reaction elementary? e. Find the rate constant and express the rate law for this reaction. f. Find the period of time between the 7th half-life and 8th half-life. ¥h. What will be the time when 37.0% of A will have reacted (t37%)?

We are doing an experiment on measuring the temperature. We are to measure the temperature of hot water (measure it initially, then wait for 10 minutes then measure again). Additionally, we are to measure the temperature of another water before and after putting ice (measure initially then measure 3 times [every 5 minutes] for 15 minutes). My question are: What law or principles of chemistry could be applied in this experiment? Should we expect the temperature of the hot water to drop? why? Should we expect the temperature of the water to rise or drop after putting the ice? why?
