In which direction will the reaction equilibrium shift: a) with an increase in temperature b) an increase

In which direction will the reaction equilibrium shift: a) with an increase in temperature b) an increase in pressure 1) CO2 (g) + CaO (s) = CaCO3 (s) + Q 2) H2 (g) + Br2 (g) = 2HBr (g) + Q 2) What is the mass of the obtained water, if 1 g of hydrogen and 16 g of oxygen entered the reaction?

1) CO2 (g) + CaO (tv) = CaCO3 (tv) + Q

a) As the temperature rises, the equilibrium will shift in the opposite direction.

b) As the pressure rises, the equilibrium will shift in the forward direction.

2) H2 (g) + Br2 (g) = 2HBr (g) + Q

a) As the temperature rises, the equilibrium will shift in the opposite direction.

b) As the pressure rises, the equilibrium will shift in the opposite direction.

3) H2 + 1 / 2O2 = H2O

n (H2) = m / M = 1/2 = 0.5 mol

n (O2) = 16/32 = 0.5 mol (e)

n (H2O) = n (H2) = 0.5 mol

m (H2O) = n (H2O) * M (H2O) = 0.5 * 18 = 9 g
