I need help urgently!!! please can somebody help me.

Answer 1

kinetic energy of a gas particle depends only on the temperature of the gas. So answer is temperature.

2)Graham's law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight.

Hence option D that is CH4 because it have less molecular mass than C2H2.

3)average molecular speed is inversely proportional to the square root of molecular mass.hence CH4 will have high molecular speed at given temperature because it have less molecular mass than other.
