Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

Looking at the standard curve above , what would be the concentration (96V / V) of an unknown solution with an absorbance of 0.3

Montano1993 [528]

The volume of the unknown solution obtained from the given standard curve is 2.57%

The linear equation produced by the standard curve is :

$y = 0.136x + 0.001$

y = absorbance ;
x = concentration in percent (v/v)

Unknown Solution with absorbance value of 0.35 ;

y = 0.35

Input the value of y into the equation.

$0.35 = 0.136x + 0.001$

Collect like terms

$0.35 - 0.001 = 0.136x$

$0.349 = 0.136x$

Divide both sides by 0.136

$x = \frac{0.349}{0.136}$

$x = 2.566$

$x = 2.57$

Hence, percentage by volume of the unknown solution will be 2.57%
