Recent exam analysis indicates that Class 12 chemistry chapters like electrochemistry, solutions, and thermodynamics contribute a major portion of the exam, making them essential for preparation.
Important Formulas to Remember
Students preparing for MHTCET 2026 must memorize these important electrochemistry formulas:
Nernst Equation
E = E° − (0.0591 / n) log Q
Where:
E = Cell potential
E° = Standard cell potential
n = Number of electrons transferred
Q = Reaction quotient
Faraday’s Law
m = (ItM) / (nF)
Where:
m = Mass deposited
I = Current
t = Time
M = Molar mass
F = Faraday constant
Memorizing these formulas helps solve numerical questions quickly in the exam.
