JEE Main Chemistry Class 11 States of Matter Questions

If values of ' b ' for two gases are same but values of 'a' are different, then the gas having a larger value of 'a" will occupy lesser volume. Since, it, will have larger force of attraction and, therefore, lesser distance between its moleucles. If values of ' a ' for two gases are same but values of ' b ', are different then the smaller value of ' b ' will occupy lesser volume and, therefore, will be more compressible.
