Answer:

A. the speed at which reactants change to products over a given time

Explanation:

The rate of reaction is a measure of the speed of a chemical reaction. In chemical kinetics, the speed at which the reaction occurs is the reaction rate.

  • The measurement of the reaction rate is based on the disappearance of a reactant or appearance of the product with increasing reaction time.
  • Rate of reaction depends on the:
  1. nature of reactants.
  2. concentration of the reactants or pressure
  3. temperature
  4. presence of catalyst
  5. sunlight

What is the volume of 11.2 g of O2 at 7.78 atm and 415 K?
irina1246 [14]

Answer:

1.53 L

Explanation:

Step 1: Given data

  • Mass of oxygen (m): 11.2 g
  • Pressure (P): 7.78 atm
  • Temperature (T): 415 K
  • Ideal gas constant (R): 0.0821 atm.L/mol.K

Step 2: Calculate the moles (n) corresponding to 11.2 g of oxygen

The molar mass of oxygen is 32.00 g/mol.

11.2 g × (1 mol/32.00 g) = 0.350 mol

Step 3: Calculate the volume of oxygen

We will use the ideal gas equation.

P × V = n × R × T

V = n × R × T / P

V = 0.350 mol × (0.0821 atm.L/mol.K) × 415 K / 7.78 atm

V = 1.53 L
