Question

Assertion: Electrode potential for the electrode $M^{n+}|M$ with concentration is given by the expression under STP conditions;
$E=E^{⊝}+\frac{0.059}{n}log\left[M^{n+}\right]$.

Reason: STP conditions require the temperature to be 273 K.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
  
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
  
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true
  
• E. Both Assertion and Reason are false

Answer 1

Answer: (D)

Assertion is false but Reason is true

$E=E^{⊝}+\frac{0.059}{n}log\left[M^{n+}\right]$
This expression is valid at 298 K (standard condition), not at 273 K (STP conditions).
