The rate of the gas-phase reaction H2 + I2 → 2 HI is given by d[I2] = k[H2 ][L2] dt rate = with k = 0.0242 L mol¬1 s-1 at 400°C. If the initial con- centration of Hz is 0.081 mol L-' and that of I, is 0.036 mol L-1, calculate the initial rate at which heat is absorbed or emitted during the reaction. Assume that the enthalpy change at 400°C is the same as that at 25°C.

In solution, chemical species as simple as H+ and OH-canserve as catalysts for reactions. Imagine you couldmeasure the [H+] of a solution containing an acidcatalyzedreaction as it occurs. Assume the reactants andproducts themselves are neither acids nor bases. Sketchthe [H+] concentration profile you would measure as afunction of time for the reaction, assuming t = 0 is whenyou add a drop of acid to the reaction.
