hope this helps, pls mark brainliest :D
Answer:
a.Low temperature
Explanation
Equation of reaction:
2NO2 <==> N2O4(g) ∆H = +ve
To cause the reaction to become darker brown means to produce more of NO2 gas. That is backward reaction.
Since the reaction is endothermic, decrease in temperature will shift the equilibrium position to the left thereby favouring backward reaction. This is in line with Me Chatelier's principle.
High pressure will rather favour forward reaction (it is not the right option).
Answer:
in position and time graphs the slope of line indicates the velocity
Answer : The amount of water lost was, 333.4 grams.
Explanation : Given,
Heat released = 753480 J
Formula used :
where,
Q = heat released = 753480 J
m = mass = ?
L = latent heat vaporization of water = 
Now put all the given values in the above formula, we get:
Thus, the amount of water lost was, 333.4 grams.
