KINETICS Practice Problems and Solutions
KINETICS Practice Problems and Solutions Name: AP Chemistry Period: Date: Dr. Mandes The following questions represent potential types of quiz questions. Please answer each question completely and thoroughly. The Solutions will be posted on-line on Monday. 5. Please do #18 in chapter 12 of your text. a. This increases the [H2], which will increase the rate, but has no effect on k b. Due to Arrhenius equation, changing temperature changes the value of k. c. Catalyst function by lowering the activation energy, so due to Arrhenius equation, changing the activation energy changes the value of k. 6. Consider the reaction: P4 + 6 H2 4 PH3. A rate study of this reaction was conducted at 298 K.
a. by using the balanced chemical equation b. by using the subscripts of the chemical formulas c. by using the coefficients of the chemical formulas d. by educated guess e. by experiment 4. The following data were obtained for the reaction of NO with O 2. [NO] o [O 2] o Initial Rate x1 x1018 1 1018 2.0 x 1018 x2 x1018 1 1018 8.0 x 1018
