Bruce Wayne analyzes a kryptonite in order to prepare if ever Clark Kent becomes rogue. The former studied a kryptonite and found that it decomposes at a rate proportional to the quantity of kryptonite present. Suppose that it is found that in 25 years approximately 1.1% of a certain quantity of kryptonite has decomposed. Determine how long it will take until 50% of the original amount of kryptonite dissipates. pls. provide complete solution with explenation. the formula we use is : dx/dt=kx

Please question 27 and 28

Chapter 13 Predicting relative forward and reverse rates of reaction in a dynamic equilibrium Hydrogen and chlorine react to form hydrogen chloride, like this: H₂(9)+Cl₂(g) → 2 HCl(g) Imagine 113. mmol of HCI are added to an empty flask, and then answer the following questions. What is the rate of the reverse reaction before any HCI has been added to the flask? What is the rate of the reverse reaction just after the HCI has been added to the flask? Greater than zero, but less than the rate of the forward reaction. Greater than zero, and equal to the rate of the forward reaction. Greater than zero, and greater than the rate of the forward reaction. Zero. Greater than zero, but less than the rate of the forward reaction. Greater than zero, and equal to the rate of the forward reaction. Greater than zero, and greater than the rate of the forward reaction. None. Some, but less than 113. mmol. 113. mmol. More than 113. mmol. Using Le Chatelier's Principle to predict the result of changing…

In any chemical reaction, the rate of the reaction can be increased by:   adding product molecules to the reaction mixture. adding water to the reaction. changing the size of the container. decreasing the temperature. increasing the concentrations of the reactants.
