Which is true about reaction rates?
Nataliya [291]

Answer:

Reaction rates are not related to spontaneity

Explanation:

A spontaneous reaction is one which occurs on its own or on some activation. Non spontaneous reactions are those which do not occur on their own and thus constant energy must be supplied to make them happen.

Reaction rate is dependent on the amount of reactants and the activation energy and not on the spontaneity of the reaction. Reactions with high activation energy are slow and reactions with low activation energy are fast.

A 20 ounce bottle of soda provides a total of 300. calories. how many kilojoules are in the soda
Yuri [45]

The ratio which denotes the relation between the two different units is said to conversion factors.

According to conversion factors, the relation between calorie and kilojoule is given as, one Calorie is equal to 4.184 kJ.

1 Cal = 4.184 kJ

Now, according to above relation, convert 300 calories into kilojoules.

300 calories =300 Cal\times \frac{4.184 kJ}{1 Cal}

= 1255.2 kJ

\simeq 1255 kJ

Thus, kilojoules present in soda is equal to 1255 kJ

ReAcTanTS and PrOducTS
telo118 [61]

Answer:

START and STOP, ReAcTanTS means START, PrOducTS means STOP

Explanation:

1. We find words 'STOP' and 'START'.

2. Let's take a look at the word 'ReAcTanTS'. Enumerate the capital letters from 1 to 5 from left to right, that is,

'1': R,

'2': A,

'3': T,

'4': T,

'5': S.

Notice that if we take a combination of 54213, we obtain a word 'start'. This has, of course, a chemical application. Reactants are the ones we start with in a chemical reaction.

3. Let's take a look at the word 'PrOducTS'. Enumerate the capital letters from 1 to 4 from left to right, that is:

'1': P,

'2': O,

'3': T,

'4': S.

Notice that if we take a combination of 4321, we obtain a word 'stop'. Similarly to the previous word, it also has a direct relationship to the chemical context. Products are formed in a chemical reaction when reactants combine. This is the point where reaction comes to and end and eventually stops if it's a typical one-sided reaction.
