✍️ Sample ESAT Questions & Answers

1. What is the role of enzymes in biological reactions?
They act as biological catalysts, lowering activation energy

Enzymes are biological catalysts that speed up reactions by lowering the activation energy without being consumed.

2. What is the area enclosed by y = x² and y = x between x = 0 and x = 1?
1/6

∫₀¹ (x - x²) dx = [x²/2 - x³/3]₀¹ = 1/2 - 1/3 = 1/6.

3. What shape does a molecule with 4 bonding pairs and no lone pairs adopt?
Tetrahedral

VSEPR theory predicts a tetrahedral geometry for 4 bonding pairs with no lone pairs (e.g., CH₄).

4. If a vector a = (3, 4), what is |a|?
5

|a| = √(3² + 4²) = √(9 + 16) = √25 = 5.

5. How many moles of NaCl are in 117 g? (Molar mass NaCl = 58.5 g/mol)
2 mol

n = mass / molar mass = 117 / 58.5 = 2 mol.

6. In ESAT Physics, what is the principle of superposition for waves?
The resultant displacement is the sum of individual displacements

Superposition states that when two or more waves overlap, the total displacement equals the algebraic sum of individual displacements.
