I just have a qs about reaction rates: if temperature is increased, does it mean that at a certain time t, there is more product produced OR does it mean that at there is the same amount of product but produced faster?
Hey there! To clarify your doubt it means that the amount of product is produced faster. This is due to the law of conservation of matter (Matter can neither be created nor destroyed but only transferred). This is how it works:
As the temperature increases, the atoms of the product collide with each other rapidly(as atoms gain kinetic energy) , and this results in a reaction. To find reaction rate use arrhenius equation:
rate = k (capital a)^a*(capital b)^b
where rate is in mol dm^-3/s, k is rate constant, A and B are concentrations in mol dm^-3, a is order of reaction in respect to concentration A and b is order of reaction in respect to capital b.
Edit: I used capital a and b since, it becomes bold when I just write A and B.
