Transcribed Image Text:3. From the following data, determine the enthalpy of formation (AH°,) for diborane, B,H;(g), at 298 K:
(1) B;He(g) + 30:(g)→B2O:(s) + 3H;O(g) AH° = -1941 kJ mol
(2) 28(s) +0:(8)>B:0:(5)
AH° = -2368 kJ mol
(3) H:(e) +0:(8)→H;O(g)
AH° = -241.8 kJ mol
4. An experimenter places 15.0 mmol of A and 18.0 mmol of B in a container. The container is heated to
600 K, and the gas-phase equilibrium A +B+ 2C+ 3D is established. The equilibrium mixture is found to
have pressure 1085 torr and to contain 10.0 mmol of C. Calculate K and AG° at 600 K, assuming ideal
gas.
5. The rate constant for the first-order decomposition of a compound A in the reaction 2 A →P is k =
2.78 x 107s at 25°C.
(a) Determine the half-life of A
(b) Determine the pressure, initially 32.1 kPa at 10 mins after the initiation of reaction
