What is the mole ratio of d to a in the generic chemical reaction? 4a + b --> c + d

Mole ratio of D to A is 1 : 4

We are given the generic chemical equation;

4A + B → C + D

We are supposed to determine the mole ratio of D to A

What is mole ratio?

For example;

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.

i just learnt this recently but i need to look through my notes again
