Based on the effect of temperature on a reaction, a change in temperature affects the rate constant K.
Based on the Arrhenius equation, the y-intercept gives the value of ln A.
From the value of the slope, the value of Ea is 42.1 J/mol.
<h3>What is the effect of temperature on a reaction?</h3>
A change in the temperature of a reaction acts to increase the rate of reaction.
- Change in temperature has no effect on the ideal gas constant.
- Change in temperature has no effect on the activation energy.
- Change in temperature has no effect on the concentration of reactants.
- Change is temperature can either lower or increase the rate constant of a reaction.
- Change in temperature has no effect on the order of reaction.
According to the Arrhenius equation, the y-intercept gives the value of ln A.
From the graph; slope = -Ea/R
Ea = -slope/R
Where;
- Ea is activation energy
- R is molar gas constant = 8.314 J/K.mol
- Slope = -350 K
Ea = -(-350)/8.314
Ea = 42.1 J/mol

Answer:
B. The student chose the correct tile, but needs to flip the tile to make the units cancel
Explanation:
Based on the reaction:
2AgNO₃(aq) + Cu(s) → 2Ag(s) + Cu(NO₃)₂ (aq)
<em>2 moles of AgNO₃ react per mole of Cu producing 2 moles of Ag and 1 mole of Cu(NO₃)₂</em>
Thus, if you want to produce 6.75moles of Cu(NO₃)₂ you need:
= 13.50 moles of AgNO₃ are needed
Thus, if you analize the tile shown by the student:
<em>B. The student chose the correct tile, but needs to flip the tile to make the units cancel</em>
Answer:
I know that Aerogel is the lightest metal in existence, but I don't think it would help much with your answer. I mean you can give it a try?
Answer:
I would say you are correct.
