What pressure will be exerted by 26g if CO2 at a temperature of 35C and a volume of 550ml?
STALIN [3.7K]

Answer:

P = 28.5 atm

Explanation:

PV = nRT => P = nRT/V

P = Pressure = ?

n = moles of sample = mass/molar mass = 26g/44g·mol⁻¹ = 0.619 mole CO₂

R = gas constant = 0.08206 L·atm/mol·K

T = temperature in Kelvin = (35 + 273)K = 308K

V = volume in Liters = 550 ml = 0.550 L

Pressure (P) = nRT/V

= (0.619 mole)(0.08206 L·atm/mol·K)(308K)/(0.550 L) = 28.5 atm

Pepsi [2]

Answer:

The K_{m} of a substrate will be "10 μM".

Explanation:

The given values are:

E_{t} = 20 \ nM

[Substract] = 40 \ \mu M

K_{cat}=600 \ s^{-1}

Reaction velocity, Vo=9.6 \ \mu M s^{-1}

As we know,

⇒  Vo=\frac{K_{cat}[E_{t}][S]}{K_{m}+[S]}

On putting the estimated values, we get

⇒  9.6=\frac{600\times 20\times 10^{-3}\times 40}{K_{m}+40}

⇒  K_{m}+40=\frac{600\times 20\times 10^{-3}\times 40}{9.6}

⇒  K_{m}+40=50

On subtracting "40" from both sides, we get

⇒  K_{m}+40-40=50-40

⇒  K_{m}=10 \ \mu M
