Methane gas can be produced by the reaction of solid carbon with hydrogen gas as follows                     C(s)   +   2 H2(g)  ⇌   CH4(g)         Kp =  0.50 A vessel containing carbon is sealed and injected initially with hydrogen to a partial pressure of 2.0 atm and with methane to a partial pressure of 2.0 atm. Is the reaction at equilibrium? If not, which way will the reaction proceed to reach equilibrium?

Phophorous-32 decays by beta emission to form sulfur-32.   (In case the picture does not show: The picture indicated that 24 P-32 decayed to 3 P-32 in 9min. )  What is the decay constant, k, for P-32?

What is the molar solubility (in M) of cadmium hydroxide, Cd(OH)2, in water? Hint:  Ksp of Cd(OH)₂ is 2.0 × 10-14

Consider the reaction of elemental bromine with elemental chlorine to make a bromochloride compound at 600 K:                                          Br2(g)  +  Cl2(g)   ⇌   2 BrCl(g)       KP = 81.0 A closed vessel at 600 K is charged with 3.00 atm of Br2(g) and 3.00 atm of Cl2(g) initially and allowed to reach equilibrium. What is the partial pressure of the BrCl (in atm) at that equilibrium?

A sample of sodium bicarbonate, NaHCO3,  is placed in a closed 1.0 L vessel at 398 K and allowed to decompose unil it reaches equilibrium according to the following equation:                                         2 NaHCO3 (s)   ⇌  Na2CO3(s) +  H2O (g)   +  CO (g)      Kp = 0.650 What is the partial pressure of CO (in atm)  at equilibrium?

Which of the following will NOT affect the rate of a reaction? temperature of reaction magnitude of enthalpy of reaction (ΔH) concentration of reactants sign of enthalpy of reaction (ΔH) physical state of reactants

The combustion of ammonia proceeds by the reaction           4 NH3    +    7 O2  →  4 NO2    +    6 H2O When the rate of appearance of H2O is 1.10 Ms-1, the rate of disappearance of O2 is          Ms-1

A sample of sodium bicarbonate, NaHCO3,  is placed in a closed 1.0 L vessel at 398 K and allowed to decompose unil it reaches equilibrium according to the following equation:                                         2 NaHCO3 (s)   ⇌  Na2CO3(s) +  H2O (g)   +  CO (g)      Kp = 0.450 What is the partial pressure of CO (in atm)  at equilibrium?
