Calculate the standard entropy change for the reaction P_4(g) + 5O_2(g) rightarrow P_4 O_10(s) using the data from the following table: Express your answer in joules per kelvin using four significant figures. Molecular systems tend to move spontaneously to a state of maximum randomness or disorder. Molecular randomness, or disorder, is called entropy and is denoted by the symbol S. As a state function, entropy change, delta S, depends only on initial and final states. delta S has a positive value when disorder increases and a negative value when disorder decreases. The following conditions usually result in an increase in entropy: a change of phase: solid rightarrow liquid rightarrow gas, an increase in the number of gas molecules, or a solid dissolving to form a solution. Although the sign of the entropy change can be predicted as described above, the actual value of delta S degree must be calculated from the absolute entropy values, S degree, of the reactants and products: delta S degree = S degree (products) - S degree (reactants) Predict the sign of the entropy change, delta S degree, for each of the following reactions. Pb^2+ (aq) + 2Cl^-(aq) rightarrow PbCl_2(s) CaCO_3(s) rightarrow CaO(s) + CO_2(g) 2NH_3(g) rightarrow N_2(g) + 3H_2(g) D. P_4(g) + 5O_2(g) rightarrow P_4 O_10(s) E. C_4 H_8(g) + 6O_2(g) rightarrow 4CO_2(g) + 4H_2 O(g) F. I_2(s) rightarrow I_2(g) Drag each item to the appropriate bin. A B C D E F
