Asample of chlorine gas is at 300. k and 1.00 atmosphere. at which temperature and pressure would the sample behave more like an ideal gas?
(1) 0 k and 1.00 atm
(2) 150. k and 0.50 atm
(3) 273 k and 1.00 atm
(4) 600. k and 0.50 atm
could you me with my questions?

Answer : The correct option is, (4) 600 K and 0.50 atm

Explanation :

The conditions for ideal gas are :

The ideal gas equation is,

The conditions for real gas are :

The real gas equation is,

A real gas behave ideally at high temperature and low pressure condition.

From the given options we conclude that, the option (4) have high temperature and low pressure. So, this is the correct option.

Hence, the sample behave more like an ideal gas at 600 K and 0.50 atm.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
