Question

Given the reaction: N2(g) +2O2(g) ⇌ 2NO2(g) The forward reaction is endothermic. Determine which of the following changes would result in more product being produced. I. Increase NO2II. Decrease O2III. Add a catalystIV. Increase the temperatureV. Increase the pressureA. IV and VB. I and IIC. II, III, and VD. II and IV

Answer 1

In this question, we have to determine which are the factors that will cause the forward reaction to be favored, causing more products to be produced, the possibilities are:

I. Increase NO2

This option would cause more reactants to be produced, since we are raising the number of products, therefore the reaction will produce more reactants to balance

II. Decrease O2

Same case as option I

Since I and II are wrong, the only option left is letter A, if you increase the temperature the endothermic reaction will be favored, and increasing the pressure, the reaction with less moles of gas will be favored, both are the case in our question

Letter A is correct
