Lorico [155]
Sugar dissolves faster in a warm liquid than in a cold liquid – this is an example of how temperature influences the reaction rate....

Yes it is. Another example is surface area of reactants, powdered iron fillings would react faster in HCl than iron lumps.

Also your beverage would also dissolve faster in hot water than in cold water, this is also an example of how temperature affects rate of reaction.

There are other examples that can be stated as well.

Hydrogen is prepared commercially by the reaction of methane and water vapor at elevated temperatures. CH₄(????) + H₂O(????) ⇌ 3
sammy [17]

Answer:

6.2846

Explanation:

Given that:-

Concentrations at equilibrium :-

[CH_4]=0.126\ M

[H_2O]= 0.242\ M

[CO]= 0.126\ M

[H_2]= 1.15\ M

The equilibrium reaction is:-

CH_4+H_2O\rightleftharpoons 3H_2+CO

The expression for equilibrium constant is:

K_{c}=\frac {\left [ H_2 \right ]^3\left [ CO \right ]}{\left [ CH_4 \right ]\left [ H_2O \right ]}

Applying the values as:-

K_c=\frac{1.15^3\times 0.126}{0.126\times 0.242}=6.2846

<u>The equilibrium constant for the reaction is:- 6.2846</u>

anygoal [31]

Answer:

The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.
