Use each equation to predict whether the relative entropy change is s(products) > s(reactants) or s(products) < s(reactants) and whether δs > 0 or δs < 0 for the chemical reaction represented. justify your answer in each case.
a. 2nh3(g)→n2(g) + 3h2(g)
b. 2al(s) + 3f2(g)→2alf3(s)

When will le chatelier's principle come into effect? at the beginning of a reaction, when there are only reactants when a reaction has reached chemical equilibrium when a catalyst is added to a reaction mixture when a reaction is occurring but not yet at equilibrium

Choose all that apply. when creating a graph, you should: determine the x- and y- variables label the scale on the x- and y- axes plot the data points draw a line of best fit to represent the data trend

If a solution is considered basic, then a) the hydroxide ion and hydronium ion concentrations are equal. b) the hydroxide ion concentration is less than the hydronium ion concentration. c) the hydronium ion concentration is greater than the hydroxide ion concentration. d) the hydroxide ion concentration is greater than the hydronium ion concentration.
