Which gases help to control the Earth’s temperature?
GaryK [48]

Answer:

carbon dioxide

Explanation:

Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide.

At a given temperature, the elementary reaction A − ⇀ ↽ − B , in the forward direction, is first order in A with a rate constant
ZanzabumX [31]

Answer:

0.24

Explanation:

We are given that

Rate constant for A=k=0.0180/s

Rate constant for  B,k'=0.0750/s

We have to find the value of equilibrium constant for the reaction

A\rightleftharpoons B

Equilibrium constant, for k=\frac{k}{k'}

Using the formula

k=\frac{0.0180}{0.0750}=0.24

Hence, the value of the equilibrium constant for the reaction

A\rightleftharpoons B at this temperature=0.24

Given the equilibrium constants for the following two reactions in aqueous solution at 25 ∘C HNO2(aq)H2SO3(aq)⇌⇌H+(aq) + NO2−(aq
krok68 [10]

Answer : The value of K_c for the final reaction is, 184.09

Explanation :

The equilibrium reactions in aqueous solution are :

(1) HNO_2(aq)\rightleftharpoons H^+(aq)+NO_2^-(aq)         K_{c_1}=4.5\times 10^{-4}

(2) H_2SO_3(aq)\rightleftharpoons 2H^+(aq)+SO_3^{2-}(aq)         K_{c_2}=1.1\times 10^{-9}

The final equilibrium reaction is :

2HNO_2(aq)+SO_3^{2-}(aq)\rightleftharpoons H_2SO_3(aq)+2NO_2^-(aq)         K_{c}=?

Now we have to calculate the value of K_c for the final reaction.

Now equation 1 is multiply by 2 and reverse the equation 2, we get the value of final equilibrium reaction and the expression of final equilibrium constant is:

K_c=\frac{(K_{c_1})^2}{K_{c_2}}

Now put all the given values in this expression, we get :

K_c=\frac{(4.5\times 10^{-4})^2}{1.1\times 10^{-9}}=184.09

Therefore, the value of K_c for the final reaction is, 184.09
