All of the following equations are statements of the ideal gas law except

a. p = nrtv
b. pv/t = nr
c. p/n = rt/v
d. r = pv/nt

The first equation, a. PV = nRT, is not a valid statement of the ideal gas law.

Explanation:

The basic expression for the ideal gas law is:

     .......... [Equation 1]

Where:

n is the number of moles of the gasV is the volume occupied by the gasp is the pressure exerted by the gas moleculesT is the temperature in absolute scale (Kelvin)R is the Universal gas constant (0.0821 atm-liter /K-mol or the equivalents in other units)

You can perform different algebraic operations to obtain equivalent equations:

Choice b) Divide equation 1 by T and you get:

pV / T = nR, which is the choice b. from your list.

Choice c) Divide equation 1 by n × V and you get:

p/n = RT / V, which is the choice c. from your list.

Choice d) Divide equation 1  n × T and you get:

pV / (nT) = R, which is the choice d. from your list.

The choice a. p = nRTV states that p and V are in direct relation, when the ideal gas law states that p and V are inversely related, so that equation is wrong.

Conclusion: the choice a, p = nRTV, is not a statement of the ideal gas law.

the answer is true.

this statement is true.
