Answer:
Increasing the temperature
Explanation:
According to le ch.atlleors principle any external pressure, temperature,change in concentration can change the equilibrium
So applying temperature comes under it
Start by writing out molar mass of each component:
1) NaOH= 22.99+16+1.01 --> 40
2) Na₃PO₄= (22.99)3 + 94.97 + 64 --> 227.94
3) NaNO₃= 22.99 + 14 + 48 --> 84.99
Now compare the mass of sodium with the rest of the substances:
1) (22.99/40)100%= 57.475%
2) (68.97/227.94)/100%= 30.25%
3) (22.99/84.99)/100%= 27.05%
As seen, the ordered list is: Sodium hydroxide, sodium phosphate and sodium nitrate.
Hope I helped :)

125cal=(60.0g)(0.0920)(T-21)
[(125)/(60)(0.0920)]+21=T2
T2=43.6C

Explanation:
Answer:
1. First
2. Third
3. Fourth
4.remain the same as
Explanation:
Given the reaction equation;
Rate= k[A] [B]^3
We can see that the order of reaction is first order with respect to reactant A and third order with respect to reactant B. This gives an overall fourth order reaction.
If the concentration of A is doubled and that of B is halved. The rate of reaction remains the same.
