Virial equation is: `PV_(M)=RT[A+(B)/(V_(M))+(C )/(V_(M^(2)))+…]`, where `A`, `B`, `C`, …. are first second,third, … virial coefficent, respectively, For an ideal gas

Options

A. `A=` unity and `B`, `C` are zero.
B. `A`, `B`, `C` are all equal to unity.
C. `A` is dependent of temperature.
D. All `A`, `B`, `C` depend on temperature.

Explanation

To solve the problem regarding the virial equation for an ideal gas, we can follow these steps:

### Step 1: Understand the Virial Equation
The virial equation is given as:
\[ PV_M = RT \left[ A + \frac{B}{V_M} + \frac{C}{V_M^2} + \ldots \right] \]
where \( P \) is the pressure, \( V_M \) is the molar volume, \( R \) is the universal gas constant, and \( T \) is the temperature. The coefficients \( A, B, C, \ldots \) are known as the virial coefficients.

### Step 2: Recall the Ideal Gas Law
