Divide both sides by <span>t
</span>
<span>a+b=r/t
</span>Subtract b <span>from both sides
</span>
a<span>=r/t-b = Solution </span>

Answer:
the answer is the first one. im sorry if im wrong. good luck though
Step-by-step explanation:
The concentration gradient represents the concept that, just as a ball rolls down a slope, during diffusion molecules move down the concentration gradient. Higher concentration gradients will result in higher rates of diffusion. As the molecules move the gradient evens out until equilibrium is reached.
