Consider the chemical reaction: 2H2O(l)→2H2(g)+O2(g)
How many moles of H2O are required to form 1.5 L of O2 at a temperature of 326 K and a pressure of 0.992 atm ?

For the reaction i2(g)+br2(g)←−→2ibr(g), kc=280 at 150 ∘c. suppose that 0.450 mol ibr in a 2.00-l flask is allowed to reach equilibrium at 150 ∘c. what is the equilibrium concentration of 2ibr, i2, br2
