Consider the following reaction, for which ∆H° = +87.9 kJ/mol and ∆S° = +170.2 J/mol·K. PCl5(g) → PCl3(g) + Cl2(g) Assume ∆H° and ∆S° do not vary appreciably with change in temperature. At what temperature will the reaction be at equilibrium when the partial pressures of each component of the reaction are under standard conditions (1.00 atm each).?

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks. energy was destroyed inside the blocks. energy was absorbed into the blocks from outside the system. energy was transferred from the warmer block to the cooler block.
