(b) a solute standard state.

 

The equation shown is: \[ p_1 = 78.8x_1e^{0.65x_2^2 + 0.18x_2^3} \] This formula represents a mathematical expression where: - \( p_1 \) is the dependent variable. - \( x_1 \) and \( x_2 \) are independent variables. - The constant 78.8 is a coefficient multiplying \( x_1 \). - \( e \) is the base of the natural logarithm, typically used to denote exponential growth or decay. - The exponent is a polynomial expression \( 0.65x_2^2 + 0.18x_2^3 \), where the terms are raised to the power of 2 and 3 respectively. This kind of equation could be used in various scientific fields to model complex phenomena where exponential factor plays a significant role.
