Answer:

290 N

Explanation:

Total downward force = Force applied on the door in bringing it down + weight of the door

Total downward force = 80 + 210

Total downward force = 290N

The equilibrium constant, Kp, has a value of 6.5 × 104 at 308 K for the reaction of nitrogen monoxide with chlorine. 2NO(g) + C
Juliette [100K]

<u>Answer:</u> The K_c for the given reaction is 2.67\times 10^{-2}

<u>Explanation:</u>

For the given chemical equation:

2NO(g)+Cl_2\rightleftharpoons 2NOCl(g)

Relation of K_p\text{ with }K_c is given by the formula:

K_p=K_c(RT)^{\Delta n_g}

where,

K_p = equilibrium constant in terms of partial pressure = 6.5\times 10^{-4}

K_c = equilibrium constant in terms of concentration = ?

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature = 308 K

\Delta n_g = change in number of moles of gas particles n_{products}-n_{reactants}=2-3=-1

Putting values in above equation, we get:

6.5\times 10^{-4}=K_c\times (0.0821\times 500)^{-1}\\\\K_c=\frac{6.5\times 10^{-4}}{(0.0821\times 500)^{-1})}=2.67\times 10^{-2}

Hence, the K_c for the given reaction is 2.67\times 10^{-2}

Which of the following stage is also known as the unstable stage?
Lelechka [254]

Transient stage is also called the unstable stage and in this stage, there is a gradual decrease in deformation rate to a definite constant value.

<h3>What is Transient stage ?</h3>

A transient state is when a process variable or variables changes, but before the system reaches a steady state.

Transient time is the time it takes for a circuit to change from one steady state to the next.

Therefore, Transient stage is also called the unstable stage and in this stage, there is a gradual decrease in deformation rate to a definite constant value.
