Consider the Following Reaction at Constant Pressure

question 62

Multiple Choice

Consider the following reaction at constant pressure. Use the information here to determine the value of ΔS_surr at 398 K. Predict whether or not this reaction will be spontaneous at this temperature. 4NH₃(g) + 3O₂(g) → 2N₂(g) + 6H₂O(g) Δ_rH = -1267 kJ

• A) ΔS_surr = +12.67 kJ K^-1 mol^-1, reaction is not spontaneous
• B) ΔS_surr = -12.67 kJ K^-1 mol^-1, reaction is spontaneous
• C) ΔS_surr = +50.4 kJ K^-1 mol^-1, reaction is not spontaneous
• D) ΔS_surr = +3.18 kJ K^-1 mol^-1, reaction is spontaneous
• E) ΔS_surr = -3.18 kJ K^-1 mol^-1, reaction is not spontaneous

Definitions:

Latent Learning

The process by which something is learned but not immediately expressed or noticeable until a later time.

Associative Learning

A learning process by which a subject links two stimuli or a behavior and a consequence.

Operant Conditioning

A learning principle where behaviors are modified by the consequences that follow them, with rewards increasing desired actions and punishments reducing their occurrence.

Predictability

The ability to accurately forecast future events or behaviors based on patterns or prior knowledge.
