Question

В колбу налили раствор сахарозы с концентрацией 0,2 моль/л; ферментов инвертазы было гидролизовано 16% сахара при температуре 23 градуса. Каким было и каким стало давление.

Answer 1

Introduction

Based on the given information, a solution of sucrose with a concentration of 0.2 mol/L was poured into a flask. Invertase enzymes hydrolyzed 16% of the sugar at a temperature of 23 degrees Celsius. The question is about the change in pressure before and after the hydrolysis.

Pressure Change

To determine the change in pressure, we need to consider the reaction that occurs during the hydrolysis of sucrose by invertase enzymes. In this reaction, sucrose is broken down into glucose and fructose. Since the reaction involves the breakdown of a solid (sucrose) into two aqueous products (glucose and fructose), the total number of moles of particles in the solution will increase. This increase in the number of moles will result in an increase in the pressure inside the flask.

Therefore, the pressure in the flask would have increased after the hydrolysis of 16% of the sugar.

Unfortunately, I couldn't find specific information about the exact change in pressure in the given search results. It would be helpful to know the initial pressure or volume of the solution to calculate the exact change in pressure.
