    How will adding an enzyme change this graph? The curved line will shift to the right. The curved line will shift to the left. The activation energy line will shift to the right. The activation energy line will shift to the left.

    An enzyme is a biological catalyst that is used to decrease the amount of energy needed for the reaction to occur

    I feel like this question is written a little funny, I think it might actually be B, if anything moves right it shows more energy since that's what is open the x axis if the graph shifted left then it would show that less energy was needed so I'm thinking it could be B @JoannaBlackwelder can you please double check this I don't want to give a wrong answer!!

    A chemical reaction is shown on a Maxwell-Boltzmann graph. What information is displayed? The activation energy required for a reaction to begin The distribution of particles with enough energy to react The half-life for the concentration of reactant particles The relationship of temperature and pressure in a reaction

    A scientist monitors the reaction between two gases in a closed container. What would happen to the rate of the reaction if the scientist increases the temperature in the container? The rate would increase because higher temperature would increase the number of collisions. The rate would decrease because the particles are unable to achieve the correct orientation. The rate would decrease because the space available for the reactions would decrease. The rate would increase because the average speed of the reactant particles would decrease.

    That one I'm pretty sure is A an increase in temperature gets the atoms move faster generating more collisions

    What procedure could you use to test the effect of a catalyst on a reaction? Add the catalyst to the reactants and then increase the temperature until the reaction occurs. Combine the reactants and the catalyst to see how long it takes them to react. Combine the reactants; when they begin to react, add the catalyst to stop the reaction. Observe the rate of the reaction and then observe it again with the catalyst included.

    In order to test the effect on anything you need your experiment and your control the experiment you would see how the catalyst changes the reaction and the control you would not put the catalyst in so D would be my answer

    Zinc reacts with excess hydrochloric acid to produce zinc chloride and hydrogen gas. What happens to the reaction rate if you increase the concentration of zinc? The reaction rate decreases because the area available for particle movement is decreased. The reaction rate decreases because the probability the reverse reaction is more likely. The reaction rate increases because the energy of each particle increases. The reaction rate increases because the probability of collisions increases.

    The reaction rate would not decrease if there was more zinc it would increase because more collisions occur

    Why does increasing the temperature of a reaction cause the reaction rate to increase? The potential energy of each particle increases. Increased energy enables more particles to collide. More collisions occur because average particle speed decreases. The average kinetic energy of the particles decreases.

    How will adding an enzyme change this graph? The curved line will shift to the right. The curved line will shift to the left. The activation energy line will shift to the right. The activation energy line will shift to the left.

    It is tricky I know that the activation energy decreases but the way it's all worded I'm not a fan
