When products form in an exergonic reaction, the <span>energy required to break bonds is less than the energy released from new bonds. This is usually given off as light. I hope this is the answer you are looking for. Looking forward to help you again. Have a great day ahead!</span>
Answer: GeH4 (Germanium(IV) Hydride)
Explanation:
A Binary molecular compound Hydrogen and a Group 4A element which is more more acidic than SiH4 in aqueous solution is GeH4.
The pKa of GeH4;
= 25
Whilst that of SiH4
= 35
The lesser the pKa the higher the Ka which means more acidic.
Freezing point is defined as the temperature needed for a liquid to turn into a solid and a melting point is the temperature needed for a solid to become a liquid. Sodium Chloride has a lower freezing point than water, as such when it is added to icy roads it helps to melt the ice faster by lowering the melting point of the water making it turn into a liquid faster/easier even if it is "cold" outside.
Answer:
l and t
Explanation:
because they are in group one
Explanation:
Rate law is defined as the rate of a reaction is directly proportional to the concentration of reactants at constant temperature.
= k
where, k = rate constant
n = order of reaction
For the given reaction,
Hence, its rate will be as follows.
Rate =
Also, it is known that slowest step in a chemical reaction is the rate determining step.
Hence, for the given rate law correct reaction is as follows.
Step 1 : (slow)
Balancing this equation it becomes (slow)
Step 2: (fast)
