1) well, it depends on the state of H2O, is it in gasous state? or liquid?
if it is vapor, increseing pressure will not affect the equilibrium, since both side have the same amout of molecules.
if it is in liquid state, incresing pressure will shift the equilibrium to the left, since increasing pressure favors a lesser volume.
(i doubt that H2O is in liquid state though, since CO2 will establish another equilibrium with water and forms H2CO3...
)
2) increasing temperature will increase the kinetic energy of the system, which can be counted as one of the "product", thus the equilbrium will shift to the left.
