Answer:

Explanation:

Variation problems involve fairly simple relationships or formulas, involving one variable being equal to one term. Here follows the most common kinds of variation.

The constant of variation in a direct variation is the constant (unchanged) ratio of two variable quantities. In the following equation y varies directly with x, and k is called the constant of variation:

y=kx

Another form of variation is the inverse variation which works when there is a relationship between two variables in which the product is a constant. When one variable increases the other decreases in proportion so that the product is unchanged.

The molar mass of a certain gas is 49 g. What is the density of the gas in g/L at STP?

snow_tiger [21]

Answer:

$\boxed{\text{2.2 g/L}}$

Explanation:

We can use the Ideal Gas Law to calculate the density of the gas.

pV = nRT

n = m/M Substitute for n

pV = (m/M)RT Multiply both sides by M

pVM = mRT Divide both sides by V

pM = (m/V) RT

ρ = m/V Substitute for m/V

pM = ρRT Divide each side by RT

$\rho = \frac{pM }{RT}$

Data:

p = 1.00 bar

M = 49 g/mol

R = 0.083 14 bar·L·K⁻¹mol⁻¹

T = 0 °C = 273.15 K

Calculation:

ρ = (1.00 × 49)/(0.083 14 × 273.15) = 2.2 g/L

The density of the gas is $\boxed{\text{2.2 g/L}}$ .

Calculate the rate constant, k k , for a reaction at 60.0 60.0 °C that has an activation energy of 80.1 80.1 kJ/mol and a freque

djverab [1.8K]

Answer:

0.24 s-1

Explanation:

We first list the parameters as shown in the image attached. The variables are now properly substituted. This equation is used to calculate the rate constant and clearly show us the dependence of the rate constant on temperature. From this equation, we can clearly and easily see that the rate constant increases exponentially with increase in temperature of the reaction system.
