In an experiment involving an enzyme, the ph is raised from 2 to 11. what will be the most likely effect of this on the reaction?

Answer;

-enzyme will denature, stopping the reaction

-Explanation;

In an experiment involving an enzyme, the effect of raising pH from 2 to 11 will be the denaturation of the enzyme and consequently stopping the reaction.

Enzymes work at a certain pH, called optimum pH, increasing the pH of an enzyme above the optimum pH affects the structure of an enzyme through denaturation and thus affecting its activity. When this happens the enzyme looses the ability to catalyze the reaction and therefore, the reaction will stop.

the maximum mass of nh3 is nh3 in grams

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
