In an experiment with Vernier calipers of least count 0.1 mm, when two jaws are joined together the zero of Vernier scale lies right to the zero of the main scale and 6th division of Vernier scale coincides with the main scale division. While measuring the diameter of a spherical bob, the zero of Vernier scale lies in between 3.2 cm and 3.3 cm marks, and 4th division of Vernier scale coincides with the main scale division. The diameter of bob is measured as
A passenger sitting in a train A moving at 90 km/h observes another train B moving in the opposite direction for 8 s. If the velocity of the train B is 54 km/h, then length of train B is:
A vector \(\sqrt{3}\hat{i} + \hat{j}\) rotates about its tail through an angle 30\(^\circ\) in clock wise direction then the new vector is
If the minimum force required to move a body up an inclined plane of inclination 45\(^\circ\) is 3 times the force required to just prevent it sliding down, the coefficient of friction is
The screening effect of d-electrons is
Chloride ion and potassium ion are isoelectronic. Then
For the reaction CO(g) + \(\frac{1}{2}\) O\(_2\)(g) \(\rightarrow\) CO\(_2\)(g) Which one of the statement is correct at constant T and P?

Step 1: Understanding the Question:
The question asks for the relationship between enthalpy change (\(\Delta H\)) and internal energy change (\(\Delta E\) or \(\Delta U\)) for a given gaseous reaction.
Step 2: Key Formula or Approach:
The relationship between enthalpy and internal energy for a reaction involving ideal gases is:
\[ \Delta H = \Delta E + \Delta n_g RT \]
where \(\Delta n_g\) is the change in the number of moles of gaseous products and reactants.
Step 3: Detailed Explanation:
Calculate \(\Delta n_g\) for the reaction: CO(g) + \(\frac{1}{2}\) O\(_2\)(g) \(\rightarrow\) CO\(_2\)(g)
Moles of gaseous products (\(n_p\)) = 1
Moles of gaseous reactants (\(n_r\)) = 1 + 0.5 = 1.5
\[ \Delta n_g = n_p - n_r = 1 - 1.5 = -0.5 \]
Since \(\Delta n_g\) is negative:
\[ \Delta H = \Delta E - 0.5 RT \]
Because \(R\) and \(T\) are positive, subtracting a positive value from \(\Delta E\) makes \(\Delta H\) smaller than \(\Delta E\).
Therefore, ΔH < ΔE.
Step 4: Final Answer:
The correct relationship is ΔH < ΔE.
Quick Tip: Just count the moles of gases!
If products have fewer moles of gas (Δng < 0), then ΔH < ΔE.
If products have more moles of gas (Δng > 0), then ΔH > ΔE.
If \(|z_1| = 2, |z_2| = 3, |z_3| = 4\) and \(|2z_1 + 3z_2 + 4z_3| = 4\), then absolute value of \(8z_2z_3 + 27z_3z_1 + 64z_1z_2\) equals
If a > 0, b > 0, c > 0 and a, b, c are distinct, then (a + b)(b + c)(c + a) is greater than
If the minimum force required to move a body up an inclined plane of inclination 45\(^\circ\) is 3 times the force required to just prevent it sliding down, the coefficient of friction is
