The table shows the conditions during two trials of a reaction. Reaction Conditions
Trial Temperature Catalyst
1 30 °C Platinum
2 35 °C Platinum

Assuming that all other conditions remain the same during the two trials, which of the following is true for the reaction?
The reaction pathway for the two trials is different.
The activation energy barrier is lower during Trial 2 than Trial 1.
More reactant particles meet the activation energy requirement in Trial 2 than Trial 1.
The number of particles having the required activation energy is the same during Trial 2 and Trial 1.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
