CHEM 152 Quiz section worksheet 1

Name:_______________

1) For the hypothetical reactions 1 and 2, K1 = 102 and K2 = 10–4. 1. A2(g) + B2(g) 2AB(g) 2. 2A2(g) + C2(g) 2A2C(g) 3. A2C(g) + B2(g) 2AB(g) + (1/2)C2(g) What is the value for K for reaction 3?

2) The value of Kp for the reaction H2(g) + O2(g) H2O2(g) is 2.3 106 at 570K. Determine the value for K for this reaction at 570K. [Hint: Remember the gas constant R = 0.0821 atm L / mol K & pay close attention to the unit of R and try to use that for conversion of atm to concentration]
