Hydrogen peroxide (H2O2) is a syrupy liquid with a relatively low vapor pressure and a normal

boiling point of 152.2 o C. Rationalize the

difference of these physical properties from those

of water

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
