Final answer:
The equation that is equivalent to the ideal gas equation PV = nRT is pv = nRT.
Step-by-step explanation:
The ideal gas equation is represented by the equation PV = nRT, where P is pressure, V is volume, n is the amount of gas in moles, T is the temperature (in K), and R is the ideal gas constant. Dividing both sides of the equation with V leads to the equation pv = nRT.
Therefore, the equivalent equation to the ideal gas equation is a) pv = nRT.
