Correct option is (4)
The Arrhenius equation is given as k = A e-Ea/RT
∴ ln k = ln A - Ea/RT
ln k v/s 1/T gives a straight line graph with slope = -Ea/R and intercept = ln A
Two statements are given below: Statement-I: The ratio of the molar volume of a gas to that of an ideal gas at constant temperature and pressure is called the compressibility factor.
Statement-II: The RMS velocity of a gas is directly proportional to the square root of \( T(K) \).
