Rate of the reaction is the decrease in concentration of the reactant or increase in the concentration of products per unit time.
Factors like concentration (pressure) of the reactant, nature of reactant, catalyst, surface area of the reactant, affect the reaction rate. Greater the concentration of the reactant, higher will be the number of effective collisions between the reactant molecules per unit time. So, the rate of reaction would increase with increase in frequency of successful collisions due to the increase in concentration of the reactants.
So, the correct answer is D. an increase in the frequency of successful collisions
Molar mass sucrose = 342.0 g/mol
V = 460 mL / 1000 = 0.46 L
Molarity = 1.10 M
mass = M * molar mass * V
mass = 1.10 * 342.0 * 0.46
mass = 173.052 g
hope this helps!
The temperature at which the substance is melting is THE SAME AS the temperature at which the substance is freezing
Answer:
The lithosphere is broken into separate sections called plates. The geological theory that states that pieces of Earth's lithosphere are in constant, slow motion, driven by convection currents in the mantle is plate tectonics.
Answer:
helium protons and electrons determine the atomic number and helium has the lowest
