Chemistry: A student measures the time it takes for two reactions to be completed. Reaction A is completedd in 12 seconds, and reaction B is completed in 2q seconds. What can you conclude about the rates of the reactions? A. The rate of reaction A is lower B. The rates of reation A and B are equal C. The rate of reaction B is lower

Rock-forming minerals are quartz, calcite, corundum, etc. These minerals cannot be broken down into smaller compositions...

A. The rate of reaction A is lower

Further explanation

The reaction rate (v) shows the change in the concentration (reduction of reactants and product additions ) per unit time

Can be formulated:

Reaction: aA ⇒ bB

$\large{\boxed{\boxed{\bold{v~=~-\frac{\Delta A}{\Delta t}}}}$

$\large{\boxed{\boxed{\bold{v~=~+\frac{\Delta B}{\Delta t}}}}$

A = reactants

B = product

v = reaction rate

t = reaction time

Time of reaction A : 12 s

Time of reaction B : 2 s

Because reaction speed/the rate of reaction is inversely proportional to the time, then A. The rate of reaction A is lower
