To tackle the question, let's recall the key thermodynamics terms involved in chemical reactions. Option 1: 'ΔG; ΔG°' This matches the standard definitions: the actual, or free-energy change for a reaction under given conditions is ΔG, while the standard free-energy change, defined under standard state conditions, is ΔG°. This option is consistent with how these terms are us......Login to view full explanation

The delta free energy of a reaction is independent of:

Which of the following statements best describes an endergonic reaction?

Ethylene (CH2=CH2) represents one of the most valuable industrial chemicals. It is commonly used to synthesis styrene (C6H5C=CH2), the building block of polystyrene, a versatile plastic used to make a wide variety of consumer products. The overall chemical synthesis of styrene is given below: C6H6(l) + CH2=CH2(g) → C6H5C=CH2(l) + H2 (g) [table] Compound | ∆Hf0 (298.15K), kJ mol-1 | S0 (298.15K), J K-1 mol-1 C6H6(l) | 48.7 | 173.26 CH2=CH2(g) | 52.47 | 219.32 C6H5C=CH2(l) | 108.0 | 240.5 H2 (g) | 0.0 | 114.7 [/table] The standard Gibbs free energy of the reaction, ∆Gr0, is 17.97 kJ mol-1 at 25.00 °C. Which of the following expressions best describes the spontaneity of the reaction?

The reaction, M2O3(s) + C(s) → M(s) + CO2(g), is spontaneous at low temperatures but non-spontaneous at high temperatures. If we assume that, since the physical states do not change, the values of ΔHTo and ΔSTo are constant over a wide temperature range, including 25.0°C, we can deduce that, over this range
