The accompanying diagram shows how ΞH (red line) and TΞS (blue line) change with temperature for a hypothetical reaction.
(b) In what temperature range is this reaction spontaneous?
Consider a reaction A2(π) + B2(π) β 2 AB(π), atoms of A shown in red in the diagram and atoms of B shown in blue. (a) If πΎπ = 1, which box represents the system at equilibrium?
Consider a reaction A2(π) + B2(π) β 2 AB(π), atoms of A shown in red in the diagram and atoms of B shown in blue. (b) If πΎπ = 1, which box represents the system at π < πΎπ?
