Look at the following equation. __Au2O3 → _Au + _02
In order to follow the law of conservation of mass, this equation must have which set of coefficients in order from left to right?
A. 2,4,3
B. 1,3,1
C. 2,1,3
D. 1,1,3

A is correct

Explanation:

AU=2x2=4           Au=1x4=4

O=3x2=6              O=2x3=6

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
