Problem 44

The decomposition of hydrogen iodide on finely divided gold at 150C is zero order with respect to HI. The rate defined below is constant at 1.20 104 mol/L s. a. If the initial HI concentration was 0.250 mol/L, calculate the concentration of HI at 25 minutes after the start of the reaction. b. How long will it take for all of the 0.250 M HI to decompose?

He survived the accident but his behavior and personality changed after the accident: lack of ability to plan, control, and assess behavior. Why is the case of Phineas Gage important to psychology It is a miracle that he survived the accident. It was the first demonstration of a relationship between brain structure and personality. It demonstrated that Gage’s cognitive functions were completely intact despite the accident. It demonstrated that humans do not need their leU prefrontal cortex. neural plasticity: change in structure, function, or organization of the brain in response to injurer experience genotype: genetic makeup Phenotype: physical characteristic Contralateral Control: left hemisphere controls right side of body, vice versa
