Question

For an endothermic reaction:
(A) \( q_p \) is negative.
(B) \( \Delta_rH \) is positive.
(C) \( \Delta_rH \) is negative.
(D) \( q_p \) is positive.
Choose the correct answer from the options given below:

• A. B and D
• B. C and D
• C. A and B
• D. A and C

Answer 1

The Correct Option is A

Endothermic reaction characteristics:
∆rH is positive: Endothermic reactions absorb heat, leading to a positive enthalpy change (∆H).
\(q_p\) is positive: At constant pressure, the heat absorbed by the system (<span class="math-tex">\(q_p\)</span>) equals the enthalpy change (∆H). As ∆H is positive for endothermic reactions, \(q_p\) is also positive.
Statements B and D are correct.
